MRAppMaster throws IllegalStateException while shutting down
------------------------------------------------------------

                 Key: MAPREDUCE-4135
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4135
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 3.0.0
            Reporter: Devaraj K


Always MRAppMaster throws IllegalStateException in the stderr while shutting down. It doesn't
look good having this exception in the stderr file of MRAppMaster container.

{code:xml}
