      Description

      The streaming job driver (org.apache.hadoop.streaming.StreamJob) does not delete the temporary JAR file it generates after a job completes. Without the fix, /var/tmp fills up with streaming job jars until they get wiped.

      The jar name is stored in the class variable 'jar_'. The JAR is generated in 'packageJobJar()' and the name stored in jar_.

      Fix: run()/submitAndMonitorJob() should clean up the jar_ file when done. Or the JAR could be generatd as a tempfile and cleaned up automatically.
