--------------------------------------

             Summary: uber job doesn't terminate on getting mapred job kill
                 Key: MAPREDUCE-5841
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5841
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 2.3.0
            Reporter: Sangjin Lee


If you issue a "mapred job -kill" against a uberized job, the job (and the yarn application)
state transitions to KILLED, but the application master process continues to run. The job
actually runs to completion.

This can be easily reproduced by running a sleep job:

{noformat}
hadoop jar hadoop-mapreduce-client-jobclient-2.3.0-tests.jar sleep -m 1 -r 0 -mt 300000
{noformat}

Issue a kill with "mapred job -kill \[job-id\]". The UI will show the job (app) is in the
KILLED state. However, you can see the application master is still running.
