This potentially creates a regression from the federation branch. In this patch, after upload of the checkpoint is done, and we see that there is no ingest, we can instantiate ingest for edits -> since after rolling the image edits.new was turned into edits. This basically will mean that if we can instantiate edits.new after saving namespace, it's going to help. If we fail there, we will do this after uploading. By doing so, in the worst case we fallback to the federation behaviour. -added check for instantiateIngest, in which if the file does not exist, we don't change the state -> otherwise standby sets the state to ingesting edits.new, ingest is not null, and standby thinks that ingest is working, where in fact it's not, and this is not a correct behavior -> ingest won't be recreated until next checkpoint !!! -ported retries for edits.new to trunk, since they were only committed to alligator, increased the number of retries to 30 -added test case to simulate edits.new failure -added some logging for failover, fixed some comment issues Test Plan: all avatar tests Reviewers: hkuang Reviewed By: hkuang Task ID: 1039092 --- .../hdfs/server/namenode/AvatarNode.java | 1 + .../hadoop/hdfs/server/namenode/Ingest.java | 4 +- .../hadoop/hdfs/server/namenode/Standby.java | 38 +++++++++++++-- .../hadoop/hdfs/TestAvatarCheckpointing.java | 47 +++++++++++++++++-- .../hadoop/hdfs/TestAvatarIngesting.java | 6 +-- .../hadoop/hdfs/server/namenode/NameNode.java | 3 ++ .../hadoop/hdfs/util/InjectionEvent.java | 2 + 7 files changed, 89 insertions(+), 12 deletions(-) diff --git a/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/AvatarNode.java b/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/AvatarNode.java index f308ac5a..4625c380 100644 --- a/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/AvatarNode.java +++ b/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/AvatarNode.java @@ -639,6 +639,7 @@ public void shutdownStandby() { protected void stopRPC(boolean interruptClientHadlers) throws IOException { try { super.stopRPC(interruptClientHadlers); + LOG.info("stopRPC: Stopping avatardatanode server"); this.server.stop(interruptClientHadlers); this.server.waitForHandlers(); } catch (InterruptedException ex) { diff --git a/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/Ingest.java b/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/Ingest.java index c98eaa9d..25e58a28 100644 --- a/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/Ingest.java +++ b/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/Ingest.java @@ -367,8 +367,8 @@ int ingestFSEdits() throws IOException { "Ingest: mismatched r/w checksums for transaction #" + numEdits); } numEdits++; - LOG.info("Ingest: Processed transaction from " + ingestFile + " opcode " + op.opCode + - " file offset " + currentPosition); + LOG.info("Ingest: Processed transaction from " + standby.getCurrentIngestFile() + + " opcode " + op.opCode + " file offset " + currentPosition); } catch (ChecksumException cex) { LOG.info("Checksum error reading the transaction #" + numEdits + diff --git a/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/Standby.java b/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/Standby.java index b92f8f79..4ca4e1a9 100644 --- a/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/Standby.java +++ b/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/Standby.java @@ -80,7 +80,7 @@ public class Standby implements Runnable{ volatile private CheckpointSignature sig; // two different types of ingested file - enum IngestFile { EDITS, EDITS_NEW }; + public enum IngestFile { EDITS, EDITS_NEW }; // allowed states of the ingest thread enum StandbyIngestState { @@ -182,6 +182,7 @@ public void run() { // if the checkpoint creation has switched off ingesting, then we restart the // ingestion here. if (ingest == null) { + InjectionHandler.processEvent(InjectionEvent.STANDBY_CREATE_INGEST_RUNLOOP); instantiateIngest(IngestFile.EDITS); } try { @@ -283,6 +284,13 @@ private void instantiateIngest(IngestFile type) synchronized (ingestStateLock) { assertState(StandbyIngestState.NOT_INGESTING); edits = getIngestFile(type); + // if the file does not exist, + // do not change the state + if (!edits.exists() + || InjectionHandler + .falseCondition(InjectionEvent.STANDBY_EDITS_NOT_EXISTS, type)) { + return; + } setCurrentIngestFile(edits); ingest = new Ingest(this, fsnamesys, confg, edits); ingestThread = new Thread(ingest); @@ -291,7 +299,7 @@ private void instantiateIngest(IngestFile type) ?

Summary: We should not try to acquire a node lock while holding its node container lock. This is because there are other code paths where the node lock is taken first and then the node container lock. Fix the deadlock by having a separate data structure to hold the runnable nodes of a type. This removes the need for iterating over the node containers.

Summary: Provide a configurable way (off by default) to timeout the RPC server of the local job tracker when there is a remote job tracker running. The timeout of the RPC server is not done normally, since the client process is expected to exit after the job is done. But for long running clients like RAID, we need to actually close the RPC server after some time. This behavior is controlled through configuration.

The source path for corrupt parity file is directory, but StripeReader.getStripeReader assumes the source path is a file and always processes source path's parent directory. This fails for corrupt parify file cases. 3. block fixer summits maxPendingJobs + 1 jobs 4. handle the exception in readTillEnd when readLen = 0 Test Plan: TestDirectoryBlockFixer ant test Reviewers: hkuang, dikang Reviewed By: hkuang Task ID: 1094352 --- .../hadoop/raid/BlockIntegrityMonitor.java | 47 +- .../hadoop/raid/BlockReconstructor.java | 5 +- .../java/org/apache/hadoop/raid/Decoder.java | 6 +- .../hadoop/raid/DirectoryStripeReader.java | 2 + .../raid/DistBlockIntegrityMonitor.java | 11 +- .../java/org/apache/hadoop/raid/Encoder.java | 21 +- .../org/apache/hadoop/raid/RaidUtils.java | 2 +- .../org/apache/hadoop/raid/StripeReader.java | 13 +- .../org/apache/hadoop/hdfs/TestRaidDfs.java | 18 +- .../hadoop/raid/TestDirectoryBlockFixer.java | 756 ++++++++++++++++++ .../hadoop/raid/TestDirectoryRaidDfs.java | 38 +- 11 files changed, 846 insertions(+), 73 deletions(-) create mode 100644 src/contrib/raid/src/test/org/apache/hadoop/raid/TestDirectoryBlockFixer.java diff --git a/src/contrib/raid/src/java/org/apache/hadoop/raid/BlockIntegrityMonitor.java b/src/contrib/raid/src/java/org/apache/hadoop/raid/BlockIntegrityMonitor.java index 6069b00b..97e5de89 100644 --- a/src/contrib/raid/src/java/org/apache/hadoop/raid/BlockIntegrityMonitor.java +++ b/src/contrib/raid/src/java/org/apache/hadoop/raid/BlockIntegrityMonitor.java @@ -22,6 +22,7 @@ import java.lang.reflect.Constructor; import java.lang.reflect.InvocationTargetException; import java.util.ArrayList; +import java.util.HashMap; import java.util.Iterator; import java.util.List; import org.apache.hadoop.conf.Configuration; @@ -254,37 +255,38 @@ protected synchronized void incrFilesCopied(long incr) { numFilesCopied += incr; } - static boolean isSourceFile(String p, String[] destPrefixes) { - for (String destPrefix: destPrefixes) { - if (p.startsWith(destPrefix)) { + static boolean isSourceFile(String p) { + for (Codec codec: Codec.getCodecs()) { + if (p.startsWith(codec.getParityPrefix())) { return false; } } return true; } - String[] destPrefixes() throws IOException { - List prefixes = new ArrayList(); - for (Codec codec: Codec.getCodecs()) { - prefixes.add(codec.getParityPrefix()); - } - return prefixes.toArray(new String[0]); - } - - static boolean doesParityDirExist( - FileSystem parityFs, String path, String[] destPrefixes) + static boolean doesParityDirExist(FileSystem parityFs, String path) throws IOException { // Check if it is impossible to have a parity file.

In the current implementation, only the 10 newest edit log back-ups are kept. Test Plan: Manual testing: * Inspected the edit log directory and after setting the checkpoint time to a low value (5 seconds), I noticed that the back-ups were created correctly and when it got to the 10th back-up edit log, the oldest one got deleted. * Restarted the HDFS service and what I mentioned at the previous point was still working. * Did various HDFS namespace operations and they were logged correctly (verified with "hadoop oev").

This will save about 30ms when reading 100KB data. 4. in Decoder.java: do the arraycopy instead of reading one by one. This will save about 10 ms when reading 100KB data.

Summary: FastCopy had a bug where it sorted both datanode lists for locality. This would cause problems in cases where we had src = {b, a , c} and dst = {b, c, d }. The final two lists would be : a, b, c and b, c, d instead of something like b, c, a b, c, d So the copies would incorrectly be performed from a->b, b->c and c->d. Test Plan: Unit tests added.

Summary: The cluster manager has a timeout on getting a response from the job tracker on thrift calls. If the job tracker is doing something time intensive and is not able to complete the thrift call, it can be timed out. This patch tries to prevent this situation from occuring. We add a SessionDriverService.Iface implementation that simply queues up the calls from the Cluster Manager during the thrift call. This will guarantee quick response times to the cluster manager. There is a separate thread to take the calls from the queue and execute them in-order. Keeping the calls in the same queue is important since that will reflect the sequence of calls that the Cluster Manager makes.

Summary: FastCopy was broken even with regular Avatar (no failovers) since it relied on the uri from the filesystem interface to determine the namenode address. In case of Avatar this uri was the logical name and not the real physical address of the machine. I've changed FastCopy such that it works with AvatarNodes before and after a failover. FastCopy still doesn't work during a failover, but I feel this is not a necessity right now since FastCopy is used as part of MR jobs which can retry failed jobs during a failover and then correctly run FastCopy again after a failover is done.

We can fire the command to coronaadmin to set the safe mode, which in turn, asks the ClusterManager to go into Safe Mode. The ClusterManager throws SafeModeExceptions on any new requests while it is in Safe Mode, and communicates to the ProxyJobTracker that it is going into Safe Mode. CoronaJobTrackers upon contacting the ClusterManager come to know that it is in Safe Mode. If they are not able to connect to the ClusterManager, while it is down for an upgrade, they try the ProxyJobTracker to find if the ClusterManager has gone down for an upgrade. While it is up, the ClusterManager does not time out any of the sessions and the nodes. Test Plan: Turn on the Safe Mode by: hadoop coronaadmin -setSafeMode Turn off the Safe Mode by: hadoop coronaadmin -unsetSafeMode 1. If you turn on the Safe Mode while a job is running, it will pause and wait for the CM to come back up in the normal state. If you turn off the Safe Mode without bringing down the ClusterManager, the execution will resume normally. Otherwise, currently the job fails because an InvalidSessionHandle exception in thrown, which will be resolved once we persist the state of the ClusterManager and restore it when it comes back up. 2.

Summary: (1) Added a new RaidNodeMetric "numFilesToFixDropped". This stands for the number of files which are detected to be corrupt in the current wake cycle of the corruptionWorker, but that are not submitted for reconstruction since number of pending jobs exceeds the limit. (2) Logging the "File_Fix_WaitTime" metric. This is the time delay between the detection of a corrupt file and the time when the reconstruction job starts execution. Test Plan: For (1) unit test : TestRaidShellFsck_CorruptCounter. The new subtest testRaidNodeMetricsNumFilesToFixDropped() should pass. For (2) Run TestBlockFixer and observe the mapreduce logs generated in the test output. There will be log entries of the form: RaidMetrics: {"maxPendingJobs":100,"maxFilesPerTask":2,"fileFixWaitTime":6723,"type":"FILE_FIX_WAITTIME"} Reviewers: dikang, weiyan, hkuang Reviewed By: weiyan --- .../hadoop/raid/BlockIntegrityMonitor.java | 2 + .../raid/DistBlockIntegrityMonitor.java | 65 +++++++++++++++---- .../apache/hadoop/raid/RaidNodeMetrics.java | 4 ++ .../TestRaidShellFsck_CorruptCounter.java | 50 ++++++++++++++ 4 files changed, 109 insertions(+), 12 deletions(-) diff --git a/src/contrib/raid/src/java/org/apache/hadoop/raid/BlockIntegrityMonitor.java b/src/contrib/raid/src/java/org/apache/hadoop/raid/BlockIntegrityMonitor.java index 97e5de89..07c221f5 100644 --- a/src/contrib/raid/src/java/org/apache/hadoop/raid/BlockIntegrityMonitor.java +++ b/src/contrib/raid/src/java/org/apache/hadoop/raid/BlockIntegrityMonitor.java @@ -94,6 +94,7 @@ public static BlockIntegrityMonitor createBlockIntegrityMonitor( private long numFileCopyFailures = 0; private long numBlockFixSimulationFailures = 0; private long numBlockFixSimulationSuccess = 0; + private long numFilesToFixDropped = 0; public volatile boolean running = true; @@ -182,6 +183,7 @@ protected synchronized void incrFileFixFailures(long incr) { numFileFixFailures += incr; } + /** * Returns the number of corrupt files that have been fixed by this * integrity monitor. diff --git a/src/contrib/raid/src/java/org/apache/hadoop/raid/DistBlockIntegrityMonitor.java b/src/contrib/raid/src/java/org/apache/hadoop/raid/DistBlockIntegrityMonitor.java index a1875a78..e474cfca 100644 --- a/src/contrib/raid/src/java/org/apache/hadoop/raid/DistBlockIntegrityMonitor.java +++ b/src/contrib/raid/src/java/org/apache/hadoop/raid/DistBlockIntegrityMonitor.java @@ -68,6 +68,8 @@ import org.apache.hadoop.raid.DistBlockIntegrityMonitor.Worker.LostFileInfo; import org.apache.hadoop.util.StringUtils; import org.apache.hadoop.util.ToolRunner; +import org.json.JSONException; +import org.json.JSONObject; /** * distributed block integrity monitor, uses parity to reconstruct lost files @@ -127,6 +129,8 @@ public class DistBlockIntegrityMonitor extends BlockIntegrityMonitor { public static final String SIMULATION_FAILED_FILE = "simulation_failed"; protected static final Log LOG = LogFactory.getLog(DistBlockIntegrityMonitor.class); + + private static final String CORRUPT_FILE_DETECT_TIME = "corrupt_detect_time"; // number of files to reconstruct in a task private long filesPerTask; @@ -213,6 +217,8 @@ public abstract class Worker implements Runnable { private long jobCounter = 0; private volatile int numJobsRunning = 0; + protected long numFilesDropped = 0; + volatile BlockIntegrityMonitor.Status lastStatus = null; long recentNumFilesSucceeded = 0; long recentNumFilesFailed = 0; @@ -268,20 +274,20 @@ public void run() { void checkAndReconstructBlocks() throws IOException, InterruptedException, ClassNotFoundException { checkJobs(); - if (jobIndex.size() >= maxPendingJobs) { LOG.info("Waiting for " + jobIndex.size() + " pending jobs"); return; } Map lostFiles = getLostFiles(); + long detectTime = System.currentTimeMillis(); FileSystem fs = new Path("/").getFileSystem(getConf()); Map filePriorities = computePriorities(fs, lostFiles); LOG.info("Found " + filePriorities.size() + " new lost files"); - startJobs(filePriorities); + startJobs(filePriorities, detectTime); } /** @@ -489,10 +495,10 @@ private void purgeFileIndex() { } // Start jobs for all the lost files. - private void startJobs(Map filePriorities) + private void startJobs(Map filePriorities, long detectTime) throws IOException, InterruptedException, ClassNotFoundException { String startTimeStr = dateFormat.format(new Date()); - + long numFilesSubmitted = 0; for (Priority pri : Priority.values()) { Set jobFiles = new HashSet(); for (Map.Entry entry: filePriorities.entrySet()) { @@ -506,26 +512,37 @@ private void startJobs(Map filePriorities) String jobName = JOB_NAME_PREFIX + "." + jobCounter + "." + pri + "-pri" + "." + startTimeStr; jobCounter++; - startJob(jobName, jobFiles, pri); + startJob(jobName, jobFiles, pri, detectTime); + numFilesSubmitted += jobFiles.size(); jobFiles.clear(); - if (jobIndex.size() >= maxPendingJobs) return; + if (jobIndex.size() >= maxPendingJobs) { + this.numFilesDropped = filePriorities.size() - numFilesSubmitted; + LOG.debug("Submitted a job with max number of files allowed.

Summary: (1) There was a memory bug in Java_org_apache_hadoop_io_nativeio_NativeIO_stat of src/native/src/org/apache/hadoop/io/nativeio/NativeIO.c. If path==NULL, there is a goto to cleanup. Cleanup frees file if file!=NULL. However, file was not initialized by this point, so sometimes you would get unlucky, and get a free on an uninitialized ptr. (2) Added clock_gettime call so we can take performance measurements in the near future. Test Plan: Run 'ant compile-native test -Dcompile.c++=true -Dlibhdfs=true -Dtest.output=true -Dtestcase=TestNativeIO'. Note, the tests won't actually run if 'test' depends on 'clean' in build.xml. If 'test' depends on 'clean', then the .so with the JNI calls will be deleted before the tests run, and the test will simply assume that all 20 tests pass. You may have to manually remove the 'clean' dependency for now, but hopefully somebody will fix this soon.

Summary: There was a bug in avatardatanode where if the RPC connection to avatar 0 is setup and then before the datanode can register to avatar 0, it goes down then when the datanode tries to register to avatar 0 it gets an exception and doesn't try to register to avatar 1. Test Plan: 1) Unit test to reproduce bug 2) All avatar unit tests.

Summary: Currently, block recovery threads interrupt BlockReceiver threads for the blocks and wait for those threads to finish processing. When the file is reopened for writing after recovering, it replace in memory size with file size by File.getLength(). However, since file syncing and closing operations can throw exception, there is no guarantee that File.getLength() will return the right size on disk. This patch improves behavior of this scenario in two ways: (1) try to call close() even when sync failed (2) Check whether on disk size matches in memory size before reopening a file This patch won't make things worse, while at least it fails the write stream in the right place. It might require much more complicatd avoid more failures when it happens, but we can leave it as a follow-up.

This has been fixed by using the right call to complete(). There was another bug where if the client creates a file and the file create succeeds on the NN, but failover occurs and hence the response doesn't reach the client. Now the client would retry the same create on the new Primary after failover and this used to fail with the AlreadyBeingCreatedException. The handling for this was incorrect in DAFS and I've corrected it accordingly. Test Plan: 1) All unit tests.

Summary: During failover each client invokes the getPrimaryRegistrationTime() call and since this is not cached every client hits zookeeper. To avoid this problem we have implemented caching for this call similar to the getPrimaryAddress() call. The caching behaves as follows : 1) If the cached file does not exist, retrieve result from ZK and populate it. 2) If this is the first time reading the value, look it up directly from the cached file. 3) If the cached file exists and this is not the first time we are reading then if the cache file has changed since the last time we read it, read the result from the cached file otherwise retrieve the result from ZK. Test Plan: 1) Unit test performs verification of the number of calls. 2) All avatar tests.

The current Map-Reduce has a single Job Tracker that reached its limits at Facebook. The Job Tracker manages the cluster resource and tracks the state of each job. In Hadoop Corona, the cluster resources are tracked by a central Cluster Manager. Each job gets its own Corona Job Tracker which tracks just that one job. The design provides some key improvements: + +- Scalability - The Cluster Manager tracks a small amount of information per job, and the individual Corona Job Trackers do the tracking of the tasks. This provides much better scalability with the number and size of jobs, and removes the need for Admission Control. +- Latency - task scheduling works in push model. A Corona Job Tracker pushes resource requests to the Cluster Manager and the Cluster Manager pushes resource grants back to the Corona Job Tracker. After receiving resource grants, the Corona Job Tracker pushes tasks to the Corona Task Tracker. This is contrast to the current Map-Reduce, where such scheduling decisions happen when heartbeats are received. The latency associated with the heartbeat model becomes important for small jobs. +- Fairness - generally Fair Scheduler in Corona does a better job of allocating fair shares of the resources to the pools when compared to Map-Reduce v1. +- Cluster Utilization - because of a lower scheduling overhead Corona does a better job of supplying Task Trackers with work. This way the cluster is more heavily utilized. + +Understanding Corona +-------------------- +A Corona Map-Reduce cluster consists of the following components: + +Cluster Manager: There is only one Cluster Manager per cluster. It is responsible for allocating slots to different Jobs (using the Fair Scheduler). The Cluster Manager only keeps track of the utilization of different machines in the cluster and the assignment of compute resources to different Jobs. It's not responsible for actually running the jobs. The Cluster Manager is agnostic to map-reduce. It can (in the future) be used to schedule compute resources for any parallel computing framework +Task Trackers: This is same as Hadoop Classic. All TT's communicate with the Cluster Manager to report available compute resources. They also communicate with the Job Trackers to actually run Map-Reduce Tasks. +Corona Job Tracker: The job tracking functionality is implemented by this. It can run in two different modes: as a part of the client running the job, or as a task on one of the Task Trackers in the cluster. The first approach gives small jobs better latencies, the second approach is better for larger jobs to minimize the amount of heartbeat traffic going in and out of the cluster. +Proxy Job Tracker: The job details page for a job is served by the Corona Job Tracker while it runs. When the job finishes the Corona Job Tracker shuts down so we need another server to show the job details. To make this seamless, the Job URL always points to a Proxy Job Tracker. While the job is running, the proxy redirects to the Corona Job Tracker. When the job is done, a file is written to HDFS, and the Proxy Job Tracker reads this file to get the job details. Additionally the Proxy Job Tracker also stores and reports all of the job metrics aggregated in the cluster.

See D525644 for stream tracing. Test Plan: 1) Replace client's core.jar with the new build/hadoop-${hadoop.version}-core.jar. 2) Update client's config. In core-site.xml, using the following key=>val properties: fs.hdfs.impl => org.apache.hadoop.hdfs.APITraceFileSystem fs.apitrace.underlyingfs.impl => org.apache.hadoop.hdfs.DistributedRaidFileSystem fs.raid.underlyingfs.impl => org.apache.hadoop.hdfs.DistributedAvatarFileSystem In core-site-custom.xml, make sure fs.hdfs.impl is not overridden. Add the following line to log4j.properties: log4j.logger.org.apache.hadoop.metrics.APITrace=DEBUG 3) Run './bin/hadoop dfs - ' for various commands on a client communicating with a test cluster. Besides producing the normal output for HDFS, there should be encoded log statements printed to stdout. The expectations for various commands are listed below: list: FileSystem.getFileStatus(/), FileSystem.listStatus, FileSystem.close put: FileSystem.close (uses copyFromLocalFile, which we currently do not trace) get: FileSystem.setVerifyChecksum, three calls to FileSystem.getFileStatus, FileSystem.open, at least one FSInputStream.read, FSInputStream.close, FileSystem.close cat: FileSystem.setVerifyChecksum, two calls to FileSystem.getFileStatus, FileSystem.open, at least one FSInputStream.read, FSInputStream.close, FileSystem.close tail: FileSystem.setVerifyChecksum, two calls to FileSystem.getFileStatus, FileSystem.open, FSInputStream.seek, at least one FSInputStream.read, FSInputStream.getPos, FSInputStream.close, FileSystem.close move: three calls to FileSystem.getFileStatus, FileSystem.rename, FileSystem.close copy: two calls to FileSystem.getFileStatus, FileSystem.open, FileSystem.getDefaultReplication, FileSystem.getDefaultBlockSize, FileSystem.create, at least one FSInputStream.read, at least one collapsed write, FSOutputStream.close, FSInputStream.close, FileSystem.close rm: three calls to FileSystem.getFileStatus, FileSystem.mkdirs(.Trash), two calls to FileSystem.getFileStatus, FIleSystem.rename (move to .Trash), FileSyste.close mkdir: FileSystem.mkdirs, FileSystem.close Reviewers: sdong, dhruba Reviewed By: sdong --- .../org/apache/hadoop/metrics/APITrace.java | 70 ++- .../hadoop/hdfs/APITraceFileSystem.java | 446 +++++++++++++++++- 2 files changed, 491 insertions(+), 25 deletions(-) diff --git a/src/core/org/apache/hadoop/metrics/APITrace.java b/src/core/org/apache/hadoop/metrics/APITrace.java index d2b89c4a..4928909b 100644 --- a/src/core/org/apache/hadoop/metrics/APITrace.java +++ b/src/core/org/apache/hadoop/metrics/APITrace.java @@ -33,29 +33,53 @@ public class APITrace { // start auto(callIds) public static final int CALL_COLLAPSED = 1;

Allow specifying a the command (in place of $JAVA_HOME/bin/java) that will be used to start the child process. This can be used to start a command that does the profiling and starts the child. This will allow us to use the Studio Analyzer collect command for profiling tasks that run on a task tracker. 2. Make corona task tracker get the number of CPUs on the machine through configuration. This, along with a suitable cpu->resource mapping on the cluster manager will let us control the number of map slots on the machine. Test Plan: tested on a single node setup.

We can fire the command to coronaadmin to set the safe mode, which in turn, asks the ClusterManager to go into Safe Mode. The ClusterManager throws SafeModeExceptions on any new requests while it is in Safe Mode, and communicates to the ProxyJobTracker that it is going into Safe Mode. CoronaJobTrackers upon contacting the ClusterManager come to know that it is in Safe Mode. If they are not able to connect to the ClusterManager, while it is down for an upgrade, they try the ProxyJobTracker to find if the ClusterManager has gone down for an upgrade. While it is up, the ClusterManager does not time out any of the sessions and the nodes. Test Plan: Turn on the Safe Mode by: hadoop coronaadmin -setSafeMode Turn off the Safe Mode by: hadoop coronaadmin -unsetSafeMode 1. If you turn on the Safe Mode while a job is running, it will pause and wait for the CM to come back up in the normal state. If you turn off the Safe Mode without bringing down the ClusterManager, the execution will resume normally. Otherwise, currently the job fails because an InvalidSessionHandle exception in thrown, which will be resolved once we persist the state of the ClusterManager and restore it when it comes back up. 2. If a job is started after the Safe Mode is turned on, it will wait for the CM to come back up in the normal state.

This was because a stale CM thrift client was being used. To solve this problem, in this diff, I am explicitly re-initializing the CM thrift client when we find that the CM is no longer in Safe Mode. Also, in the getPJTClient() method, I am now creating a client to the PJT only once in the beginning, instead of every time. Test Plan: Try to put the CM in Safe Mode, while a job is running. Then bring down the CM and unset the Safe Mode. The job should not get a TException, although it might die because of other exceptions since we haven't yet committed D519140 and D524393.

Test Plan: I couldn't find a way to test the code completely as such. I tested in two basic ways: (a) Print out what was being read (b) After we recover from the safe mode and reconstruct the state, persist the state again in a different file, and compare. The second method however requires turning off the compression and turning on pretty printing.

Summary: We don't want to trace FileSystem.close(), as this method appears to shut down scribe tracing, so our trace statement causes an exception. We also now use log4j's .info instead of .trace since .trace is not commonly used and we want to avoid any potentially querky behavior. Test Plan: Set "fs.hdfs.impl" to "org.apache.hadoop.hdfs.APITraceFileSystem" in core-site.xml. Run a simple command using the client util (e.g., 'hadoop dfs -ls /'). Make sure we don't print the final close on FileSystem. Make sure log4j messages are the the INFO level.

When starting hadoop instances via `hadoop-daemon.sh` script, it it at first sources `hadoop-env.sh` file. After some sequence of actions, it runs `hadoop`, which in turn sources `hadoop-env.sh` as well. As a result CLI arguments are doubled. So far it turned out that some of java arguments mustn't appear twice in the command line or JVM won't start (particularly I encountered it with -Xrunjdwp argument).

Summary: During failover some percent of datanodes might not report back and if this percent is low something like 0.1%, it might be safe to automatically leave safe mode instead of waiting for manual intervention. For this purposes I've implemented a datanode report threshold similar to the safe block threshold. Test Plan: 1) All avatar unit tests.

This diff does that. Doing so, has two benefits: 1. We do not get an InvalidSessionHandle excpetion when a job which has got a sessionId before the CM is in safe mode and is being upgraded, and then tries to submit a job when it comes back. Otherwise, it fails the check in the addSession() method of the SessionManager. 2. We can see how long the CM has been up without any 'perceived' downtime. This gives us some bragging rights :) Test Plan: 1. Bring down and bring up the CM normally. The startTime should be the current time. 2. Bring down the CM after going into safe mode and then persisting the state. The startTime should be the old startTime.

But SessionManager uses its own value of startTime, hence the problem continued to occur. In this diff, we make sure that both of them have the same value of startTime. Hence, when the CM comes back up, the SessionManager has the original value of startTime. Therefore, any jobs that were assigned a SessionId, but could not make the 'startSession()' request before the restart, won't get an InvalidSessionHandle exception. Also, when the CM goes into safe mode, if the last assigned SessionId was XYZ.N, the first SessionId assigned after the restart would be XYZ.N+1. Where XYZ is the timestamp of the CM's actual restart, and N is the number of sessions started in the CM's lifetime. Test Plan: 1. Put the CM in Safe Mode 2. Persist the CM state 3. Restart the CM 4. Ensure that the new SessionIds are as expected. 5. Ensure that a job which has got a sessionId before the CM was in safe mode, and actually gets to submit a startSession() request after the restart, doesn't get an InvalidSessionHandle exception.

Summary: A zookeeper client connection to the zk servers is kept open until we don't stop the DistributedAvatarFileSystem. This is really bad since it can lead to long running zk client connections.

Summary: There was a race condition in the refreshNameNodes method of AvatarDataNode where refreshNamenodes() would stop the servicePair thread to a particular namenode and would not wait for that thread to exit. Now when this thread exited it would remove out a particular namenode from the namenodeThreads map. The problem with this is that before the thread could exit another refreshNode call might add that namenode in and when our old servicePair thread exits it removes the namenode from the list of threads causing an inconsistency. Hence I've added a join() on the thread for this purpose and also put it under the refreshNamenodesLock() to avoid any race conditions. Test Plan: Run TestAvatarRefreshNamenodes 10 times which was failing because of this race condition.

Test Plan: 0) First, disable the cm.configured.pools.only setting from singleNodeHadoop/coronaConf/mapred-site.xml. It is very strange because you can't pass both the pool setting and the child.java.opts. The GenericOptionsParser will only parse the first -D option and the SleepJob will complain about whatever more -D property arguments you pass. 1) Before patching, observe task doesn't start by running: hadoop jar build/hadoop-0.20.1-dev-examples.jar sleep -Dmapred.reduce.child.java.opts="-Xmx200m -Xms200m" -m 1 2) After patching, confirm it is fixed running the same command.

Refactor the blockReceiver logic to make it possible to allow two kind of logics. BlockWithChecksumFileWriter implements exactly the same block receiving logic as before. No behavior change. Codes were directly copied as much as possible. BlockInlineChecksumWriter implements the logic for inline checksum format. The codes are not enabled. So there should have not any function change after the patch.

Summary: For protocols other than ClientProtocol, we need to use the same failover logic. For example for the balancer we might need the same piece of logic for NamenodeProtocol to do a failover. For this purpose I'm decoupling the failover logic so that it can be reused easily. I also removed some zookeeper watcher stuff that was not being used. Test Plan: All avatar unit tests.

Specifically it was happening because there were threads that are non-daemon and they keep on running even after the main() part of the taks finishes. This way we create a 'kill' command to be run X seconds later and kill the JVM is the task is reported as done. We were already doing that but only when the jvm shell execution exited, this also does it when the java process is still running and not returning, but the task is reported as done. Test Plan: I tested it manually in my single node setup. Having a job that simulates the problem (launching threads that won't die after the map task is done).

This only affects places where a rpc call returns Stringi or String[], NOT a complex object with String members. 4) Couple of places that I observed introduce overhead when writing responses (e.g., DatanodeID, DatanodeInof, BlocksWithLocations, HdfsFileStatus) - in all those places we are writing ascii strings (e.g., datanode ids), and we can do it much faster with this patch. Alltogether this cuts several percent on average for rpc calls when I do experiments in my dev server (including the call itself), by cutting up to 50% the time to set up the reponse for clients. I speculate only for strings shorter than 1000 bytes, which will definitely catch all class names (with packages) and method names. --------------------------------------------- Test Plan: manually, added test case to make sure the optimized writes fall back to normal writes for non-ascii characters.

Summary: Four changes: (1) do log collapsing for non-positional reads like we do for writes; (2) stop tracing getPos; (3) delete unused method, setStreamTracer(); and (4) trace PIDs. The first two changes help us avoid tracing 100K's of messages for each MapReduce task. Test Plan: Compiled classes for APITrace.java and APITraceFileSystem.java. Added the resulting classes and inner classes to the distribution JAR for MRDEV. Replaced hadoop-0.20-core.jar on a single datanode in MRDEV with my .jar and changed configs on that machine to use APITraceFileSystem. Run hive queries that cause logs to be collected.

Summary: I didn't try to generalize the patch as it looks like that we can't generalize it to satisfiy HBase's requirement without big efforts. So instead I narrow down the patch to only working with pread local read case. I also manged to remove two setting variables in the patch. I want to first hear from people whether they are comfortable with the approach.

This patch reverts the previous behaviour on startup with empty edits. In this situation we do not roll the log, but just append to edits. This bug happens only when failover is triggered after Standby.doCheckpoint closes the log, and before is finishes to save the namespace ONLY during the FIRST checkpoint after standby's startup. Test Plan: adjusted revious test cases to ensure that the startup with empty edits appends to edits, and does not roll the log I will try to add a testcase when the failover happens in the situation described above, but this "startup rolling" logic will be gone anyways once I start merging the new layout.

It will be a part of inline checksum patch. I want to check in these refactoring changes to trunk to avoid future merging trouble. This change is also good for overall codes. Basic idea: 1. Instead of maintaining its own File reference for data file, ActiveFile will save the DatanodeBlockInfo object and uses its File reference for data file. In this way, it is easier maintainable as there is no need to duplicate this information. In inline checksum patch, three more variables will be added: isInlineChecksum, checksumType and bytes per checksum. With this new structure, it can be handled easily. Otherwise, it will be more painful. 2. Make a common ReplicaToRead information so that no matter a reader needs to read from ActiveFile or DatanodeBlockInfo, it is able to always use the object, without having to execute complicated checking in many places.

In those functions, accessTime change is disabled. setTimes, append/overwrite files, and close will not change the accessTime. For touch, option -a and option -d have no impact to accessTime anymore. If a file is created by -a or -d, the file's accessTime is the time system creates the file. setTimes after that call has no impact. For copyFiles, the dest files' accessTime is the time that the system creates the file. setTimes to the srcFile's accessTime is ignored. Test Plan: A new test class TestAccessTime is added.

Summary: The equals method in FileStatus only compares the path and not all other information. I added in a new method in FileStatus which compares all other information for FileStatus as well. This is now used by FileStatusExtended instead of the older equals method. This is important since FileStatusExtended.equals() is used by the test framework for Avatar failovers. Test Plan: Run all avatar tests.

We can no longer store md5 in version file, since we can have multiple images in a storage directory. This patch introduces utilities for writing a computed md5 into a file. AtomicFileInputStream is a class to guarantee that the hash is written atomically (using temporary file, and rename). MD5FileUtils is a class for writing, reading, and validating md5 digests.

Bookkeper can be specified by bookkeeper:/... By default, uris without specified schema are treated as file journals/image directories. This patch temporarily changes Avatar initialize function(), once we introduce new layout, this will change. For now, if the configuration specifies something different than files, the avatar initialize will crash. -removed some code from Avatar identical to NameNode.

Summary: With this patch, we are going to have substantial savings on writing to edit log, as all longs, shorts, will be written in binary form without expensive transformations into utf8 strings (coding,decoding). Also for each operations, we will not be writing the length of writables. This change is compatible with Apache image layout -39 -> in our case it will be -40, since we have a shift for hardlinks.

Since I try to obtain the streams gradually with retries, the last stream that does not exist will cause 30 retries before the standby quiesces 2) The biggest problem that I see now is with the catchUp concept. For now it's implemented in a way where ingest looks if it's consuming the inprogress segement. If so, it checks the size of the stream and the current position and compares them. If it's consuming a finalized segment, we assume that it's caching up. This means that BK EditLogInputStream must implement lenght() method for in progress segments at least, which would give byte size of the stream. ---------------------- All tests, including new ones work, but I'm still working on this patch. Added tests for -ingest recover -reprocessing ingest -retries when obtaining input stream -------------------- I removed snapshot from compiling, because the new layout is not there at all!! I also made some changes in OfferService.java and Client.java, which are in the trunk, which fixed the timing out test cases.

I checked that on dfs1, average transaction count is below 100bytes (~90 or so), so I think it's a fair and round assumption to make that the transaction is about 100 bytes long. Hence, if the old key is present the transaction count for checkpoint is inferred by dividing the isze over 100. I also added the fs.checkpoint.txns to core-default instead of fs.checkpoint.size Test Plan: added testcase Reviewers: pritam, hkuang, avf Reviewed By: pritam --- .../hadoop/hdfs/server/namenode/Standby.java | 2 +- .../hadoop/hdfs/TestAvatarCheckpointing.java | 17 +++++ src/core/core-default.xml | 6 +- .../hadoop/hdfs/server/namenode/FSImage.java | 2 +- .../namenode/NNStorageConfiguration.java | 17 +++++ .../server/namenode/SecondaryNameNode.java | 2 +- .../namenode/TestNNStorageConfiguration.java | 67 +++++++++++++++++++ 7 files changed, 107 insertions(+), 6 deletions(-) create mode 100644 src/test/org/apache/hadoop/hdfs/server/namenode/TestNNStorageConfiguration.java diff --git a/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/Standby.java b/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/Standby.java index 2613f607..32981c55 100644 --- a/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/Standby.java +++ b/src/contrib/highavailability/src/java/org/apache/hadoop/hdfs/server/namenode/Standby.java @@ -813,7 +813,7 @@ void initSecondary(Configuration conf) throws IOException { // Initialize other scheduling parameters from the configuration checkpointEnabled = conf.getBoolean("fs.checkpoint.enabled", false); checkpointPeriod = conf.getLong("fs.checkpoint.period", 3600); - checkpointTxnCount = conf.getLong("fs.checkpoint.txns", 40000); + checkpointTxnCount = NNStorageConfiguration.getCheckpointTxnCount(conf); // initialize the webserver for uploading files.

Summary: Fixed the following things : 1) After the standby restarts we were using Thread.sleep(2000) to wait for a checkpoint to happen, this might not always be true so I modified it to a deterministic check which ensures lastCheckPointTime != 0. 2) In testQuiesceInterruption we have a stopOnEvent and waitUntilEvent, the desired behavior is first stopOnEvent occurs and then we do the quiesce. At times what can happen is before stopOnEvent occurs we start the quiesce and hence get an incorrect result. Test Plan: Run the test.

Summary: At times even when the zookeeper node is NULL, we need the functionality to still start the primary/standby avatar. One usecase is while upgrading small HBase clusters instead of failing over to a standby we can simply restart the primary and do a rolling upgrade.

DFSUtil.getInfo... tries to obtain federated addresses, and when it fail it retrieves the default value. It does not check non-federated avatar setups. The outcome is that in both cases we get information from the primary. I cleaned this code, and fixed the bahaviour. Now, for avatar setups, it first checks the federation addresses, and then tries to obtain non-federated avatar addresses, by comparing the given namenode address to fs.default.name 0 & 1 addresses.

With corona, we should avoid killing jobs during process shutdown. One, it can block process exit if the kill blocks. Two, the cluster manager will kill the session any way after process exit. So we should set webinterface.private.actions=false for corona. But this config is also used to decide if "Kill Job" is displayed in the job web UI. So the "Kill Job" should always be displayed. Once this goes in we can set webinterface.private.actions=false for our cluster. Currently there are several hive client processes stuck in process exit, and that is making several sessions hang on.

Summary: There was a bug in CachingAvatarZookeeperClient where it wouldn't close the RandomAccessFile once it was done with the locking. This caused a lot of open fds and subsequently caused failures. Test Plan: 1) All unit tests Ran TestAvatarContinuousFailover 1) Before the fix lsof showed many open fds for the lock file. 2) After the fix lsof shows no open fds for the lock file.

By default: 32768 65534 I checked a few machines on Jenkins, and this range is pretty much taken in half (15000 or so) by connections to mcrouter or mcproxy). I think this explains why taking the random port might be a regression if taken from the full range. Before we were always starting from 10K, so we would almost never go beyond 32K. With this diff I decrease the max port to 32000. I don't know what the dynamics of the MC connections is, but if they are frequently changin, this might interfere with our tests.

With this patch, I limit the number of such unsuccessful checkpoints to 10, after which the standby exits. I am not sure, is it better to throw a RuntimeException, or just unconditionally exit the standby?

Though the syntax of SED scripts +is not coincise, autoconf tool utilizes only `substitute` command. + +The substitution command basically looks like this: + +``` +s:cat:dog:g +``` + +This example will substitute every 'cat' for 'dog'. The 's' letter stands for +'substitute' command, and the trailing 'g' is a flag that enforces sed to substitute +every entry of 'cat'; otherwise it would be done only for first occurences of +'cat' per line. + +Any symbol could be used as a command delimeter. Thus said, the followings are fully +equal to the previous example +``` + s_cat_dog_g + s%cat%dog%g + s/cat/dog/g +``` + +This feature could be utilized to avoid escaping inside of sed scripts. Consider +looking at the following example +``` + s:some-folder:/tmp/foo:g + s_URL_localhost:7777_g +``` + + +How do I add new datanode configuration file? +--------------------------------------------- + +1. create a file with the name that matches format 'avatar-datanode-*.sed' +(the format of the datanode configuration files is specified by +`$DATANODE_CONFIG_FILES` variable in `config.sh` file) + +2. Fill in the file with the following content +``` +s:{{DataNode-volumes}}:[,...]:g +``` + + +What is an example of datanode config file with multiple volumes? +----------------------------------------------------------------- + +A datanode with two volumes, each resides in its own directory, will look the +following way + +``` +s:{{DataNode-volumes}}:/tmp/mydatanode-volume-1/,/tmp/mydatanode-volume-2/:g +``` + +So the directories should be listed one after another, separated with comma +delimeter. +NOTE: Make sure you do not put any spaces! + + +What exactly does autoconf tool do? +----------------------------------- + +Whenever autoconf tool starts some HDFS instance, it does the following +sequence of actions: + +1.
