Jason Lowe created MAPREDUCE-4741:
-------------------------------------

             Summary: WARN and ERROR messages logged during normal AM shutdown
                 Key: MAPREDUCE-4741
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4741
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: applicationmaster, mrv2
    Affects Versions: 2.0.1-alpha, 0.23.3
            Reporter: Jason Lowe
            Priority: Minor


The ApplicationMaster is logging WARN and ERROR messages during normal shutdown, and some
users are misinterpreting these as serious problems.  For example:
