Cloudbreak

• Documentation: https://docs.cloudera.com/management-console/cloud/index.html

Local Development Setup

As of now this document focuses on setting up your development environment on macOS. You'll need Homebrew to install certain components in case you don't have them already. To get Homebrew please follow the install instructions on the Homebrew homepage: https://brew.sh

As a prerequisite, you need to have Java 11 installed. You can choose from many options, including the Oracle JDK, Oracle OpenJDK, or an OpenJDK from any of several providers. For help in choosing your JDK, consult Java is Still Free.

You'll need Docker. For Mac, use Docker Desktop for Mac. Please allocate at least 5 CPU and 8GB Memory to the process.

Cloudbreak Deployer

The simplest way to setup the working environment to be able to start Cloudbreak on your local machine is to use the Cloudbreak Deployer.

First you need to create a sandbox directory which will store the necessary configuration files and dependencies of Cloudbreak Deployer. This directory must be created outside of the cloned Cloudbreak git repository:

mkdir cbd-local
cd cbd-local

The next step is to download the latest cloudbreak-deployer onto your machine:

curl -s https://raw.githubusercontent.com/hortonworks/cloudbreak-deployer/master/install-dev | sh && cbd --version

Add the following to the file named Profile under the cbd-local directory you have just created. Please note, when a cbd command is executed you should go to the deployment's directory where your Profile file is found (cbd-local in our example). The CB_SCHEMA_SCRIPTS_LOCATION environment variable configures the location of SQL scripts that are in the core/src/main/resources/schema directory in the cloned Cloudbreak git repository.

Please note that the full path needs to be configured and env variables like $USER cannot be used. You also have to set a password for your local Cloudbreak in UAA_DEFAULT_USER_PW:

export CB_LOCAL_DEV_LIST=cloudbreak,redbeams,environment,environmentservice,datalake,freeipa
export UAA_DEFAULT_SECRET=cbsecret2015
export CB_SCHEMA_SCRIPTS_LOCATION=/Users/YOUR_USERNAME/YOUR_PROJECT_DIR/cloudbreak/core/src/main/resources/schema
export ENVIRONMENT_SCHEMA_SCRIPTS_LOCATION=/Users/YOUR_USERNAME/YOUR_PROJECT_DIR/environment/src/main/resources/schema
export ULU_SUBSCRIBE_TO_NOTIFICATIONS=true
export CB_INSTANCE_UUID=$(uuidgen | tr '[:upper:]' '[:lower:]')
export CB_INSTANCE_NODE_ID=5743e6ed-3409-420b-b08b-f688f2fc5db1
export PUBLIC_IP=localhost
export VAULT_AUTO_UNSEAL=true
export DPS_VERSION=2.0.0.0-142

In order to run Cloudbreak, Periscope, Datalake, FreeIPA, Redbeams, Environment, Auth Mock, IDBroker Mapping Management, and Environments2 API services locally (from IDEA or the command line), put this into your Profile:

export CB_LOCAL_DEV_LIST=cloudbreak,periscope,datalake,freeipa,redbeams,environment,auth-mock,idbmms,environments2-api

Containers for these applications won't be started and Uluwatu (or the cdp & dp CLI tools) will connect to Java processes running on your host. You don't have to put all of the applications into local-dev mode; the value of the variable could be any combination.

You need to login to DockerHub:

docker login

And then provide your username and password.

Then run these commands:

cbd start
cbd logs cloudbreak

In case you see org.apache.ibatis.migration.MigrationException at the end of the logs run these commands to fix the DB and the re-run the previous section (cbd start and logs):

cbd migrate cbdb up
cbd migrate cbdb pending

For some reason if you encounter a similar problem with Periscope, Datalake, FreeIPA, Redbeams, or Environment, then run the following commands and you can restart the Cloudbreak Deployer:

cbd migrate periscopedb up
cbd migrate periscopedb pending

cbd migrate datalakedb up
cbd migrate datalakedb pending

cbd migrate freeipadb up
cbd migrate freeipadb pending

cbd migrate redbeamsdb up
cbd migrate redbeamsdb pending

cbd migrate environmentdb up
cbd migrate environmentdb pending

You can track any other application's logs to check the results by executing the following command:

cbd logs periscope # or datalake, freeipa, redbeams, environment, auth-mock, idbmms, environments2-api

If everything went well then Cloudbreak will be available on https://localhost. For more details and config parameters please check the documentation of Cloudbreak Deployer.

The deployer has generated a certs directory under cbd-local directory which will be needed later on to set up IDEA properly.

If not already present, you shall create an etc directory under cbd-local directory and place your Cloudera Manager license file license.txt there. This is essential for Auth Mock to start successfully. (Request a licence from us)

Linux difference

Cloudbreak Deployer is unable to determine the IP address on a Linux machine. Therefore, you must add in the public IP address manually to your Profile.

export PUBLIC_IP=127.0.0.1

IDEA

Check out the Cloudbreak repository

Go to https://github.com/hortonworks/cloudbreak, either clone or download the repository, use SSH which is described here: https://help.github.com/articles/connecting-to-github-with-ssh/

Project settings in IDEA

In IDEA set your SDK to your Java version under:

Set project SDK

File -> Project Structure -> Project Settings -> Project -> Project SDK -> 11

Set project Language level

File -> Project Structure -> Project Settings -> Project -> Project Language Level -> 11

Set Gradle JVM

IntelliJ IDEA -> Preferences -> Build, Execution, Deployment -> Gradle -> Gradle JVM -> 11

Import project

Cloudbreak can be imported into IDEA as a Gradle project by specifying the cloudbreak repo root under Import Project. Once it is done, you need to import the proper code formatter by using the File -> Import Settings... menu and selecting the idea_settings.jar located in the config/idea directory in the Cloudbreak git repository.

Also you need to import inspection settings called inpsections.xml located in config/idea:

IntelliJ IDEA -> Preferences -> Editor -> Inspections -> Settings icon -> Import Profile

Cloudbreak integrates with GRPC components. This results in generated files inside the project with big file sizes. By default IDEA ignores anything that is more than 8MB, resulting in unknown classes inside the IDEA context. To circumvent this, you need to add this property to your IDEA properties.

Go to Help -> Edit Custom Properties..., then insert

#parse files up until 15MB
idea.max.intellisense.filesize=15000

Restart IDEA, and Rebuild.

Running Cloudbreak in IDEA

To launch the Cloudbreak application execute the com.sequenceiq.cloudbreak.CloudbreakApplication class (set Use classpath of module to cloudbreak.core.main) with the following JVM options:

-Dcb.db.port.5432.tcp.addr=localhost
-Dcb.db.port.5432.tcp.port=5432
-Dserver.port=9091
-Daltus.ums.host=localhost
-Dvault.addr=localhost
-Dvault.root.token=<VAULT_ROOT_TOKEN>
-Dcb.enabledplatforms=""

Replace <VAULT_ROOT_TOKEN> with the value of VAULT_ROOT_TOKEN from the Profile file.

The database migration scripts are run automatically by Cloudbreak, but this migration can be turned off with the -Dcb.schema.migration.auto=false JVM option.

Configure Before launch task

In order to be able to determine the local Cloudbreak version automatically, a Before launch task has to be configured for the project in IntelliJ IDEA. The required steps are the following:

1. Open Run/Debug Configurations for the project
2. Select your project's application
3. Click on Add in the Before launch panel
4. Select Run Gradle Task with the following parameters
   1. Gradle project: cloudbreak:core

Database development

If any schema change is required in Cloudbreak services databases (cbdb / periscopedb / datalakedb / redbeamsdb / environmentdb / freeipadb), then the developer needs to write SQL scripts to migrate the database accordingly. The schema migration is managed by MyBatis Migrations in Cloudbreak and the cbd tool provides an easy-to-use wrapper for it. The syntax for using the migration commands is cbd migrate <database name> <command> [parameters] e.g. cbd migrate cbdb status. Create a SQL template for schema changes:

cbd migrate cbdb new "CLOUD-123 schema change for new feature"

As as result of the above command an SQL file template is generated under the path specified in CB_SCHEMA_SCRIPTS_LOCATION environment variable, which is defined in Profile. The structure of the generated SQL template looks like the following:

-- // CLOUD-123 schema change for new feature
-- Migration SQL that makes the change goes here.



-- //@UNDO
-- SQL to undo the change goes here.

Once you have implemented your SQLs then you can execute them with:

cbd migrate <database-name> up

Make sure pending SQLs to run as well:

cbd migrate <database-name> pending

If you would like to rollback the last SQL file, then just use the down command:

cbd migrate <database-name> down

On order to check the status of database

cbd migrate <database-name> status

#Every script that has not been executed will be marked as ...pending... in the output of status command:

Gradle is used for build and dependency management. The Gradle wrapper is added to the Cloudbreak git repository, so building can be done with:

./gradlew clean build

How to reach CM UI directly(not through Knox)

With the current design on the cluster's gateway node there is an NGiNX which is responsible for routing requests through Knox by default. But there are cases when the CM UI needs to be reached directly. It is possible on the same port by the same NGiNX on the clouderamanager/ path of the provisioned cluster.

For example: https://tb-nt-local.tb-local.xcu2-8y8x.workload-dev.cloudera.com/clouderamamanger/

Be aware of that this routing mechanism is based on cookies, so if you have problems to reach the CM UI directly especially when you reached any service through Knox previously then the deletion of cookies could solve your issues.
