Hadoop Streaming (StreamJob) does not delete temporary job/package jar
----------------------------------------------------------------------

                 Key: HADOOP-7263
                 URL: https://issues.apache.org/jira/browse/HADOOP-7263
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 0.21.0, 0.20.2, 0.20.3, 0.20.4
            Reporter: Greg Wittel
            Priority: Minor


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.
