[jira] [Created] (MAPREDUCE-4951) Container preemption interpreted as task failure

Sandy Ryza created MAPREDUCE-4951:
-------------------------------------

             Summary: Container preemption interpreted as task failure
                 Key: MAPREDUCE-4951
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4951
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: applicationmaster, mr-am, mrv2
            Reporter: Sandy Ryza
            Assignee: Sandy Ryza


When YARN reports a completed container to the MR AM, it always interprets it as a failure.  This can lead to a job failing because too many of its tasks failed, when in fact they only failed because the scheduler preempted them.

MR needs to recognize the special exit code value of -100 and interpret it as a container being killed instead of a container failure.
