Spark Works E2Data Analytics Kernels

This is a sample for the E2Data Spark Works kernels with plain java
It computes min, max, sum and average values of a primitive double array
The main class is the AnalyticsSampleEngine and accepts as arg either a number indicating the number of double values randomly generated or a text holding the path of a csv file that contains comma separated measurements in the following notation: urn,timestamp.value

Running AnalyticsSampleEngine

  1. In project's root dir, compile the classes with javac -d ./ src/net/sparkworks/e2data/*.java

  2. Make an executable jar jar cvfm analytics.jar META-INF/MANIFEST.MF /net/sparkworks/e2data/*.class

  3. Execute it with java -jar analytics.jar 100 for 100 random values or java -jar analytics.jar /path/to/file.csv to load values from a csv file. A sample csv file is available in dataset.csv
