[jira] [Created] (MAPREDUCE-5888) Failed job leaves hung AM after it unregisters

Jason Lowe created MAPREDUCE-5888:
-------------------------------------

             Summary: Failed job leaves hung AM after it unregisters 
                 Key: MAPREDUCE-5888
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5888
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mr-am
    Affects Versions: 2.2.0
            Reporter: Jason Lowe
            Assignee: Jason Lowe


When a job fails the AM hangs during shutdown.  A non-daemon thread pool executor thread prevents the JVM teardown from completing, and the AM lingers on the cluster for the AM expiry interval in the FINISHING state until eventually the RM expires it and kills the container.  If application limits on the queue are relatively low (e.g.: small queue or small cluster) this can cause unnecessary delays in resource scheduling on the cluster.
