Usage / Goals:

Warning: the project is in its pre-infancy serving a very limited purpose at the moment of packing files. More use cases are planned down the pipeline.

• pack:

Currently a single goal is available called as 'pack' that creates the jar file to be submitted to the hadoop job engine.

The jar contains a directory called ./lib , that contains all the dependent jars in the same. The classes of the current project are also available in the same.

The jar would be created in $basedir/target/hadoop-deploy/${ant.project.name}-hdeploy.jar .

$ mvn hadoop:pack

Once created , this could be submitted to the hadoop jar engine

$ $HADOOP_HOME/bin/hadoop jar $basedir/target/hadoop-deploy/${ant.project.name}-hdeploy.jar job.launching.class
