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

             Summary: NM warns about stopping an unknown container under normal circumstances
                 Key: YARN-455
                 URL: https://issues.apache.org/jira/browse/YARN-455
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 0.23.6, 2.0.3-alpha
            Reporter: Jason Lowe


During normal operations the NM can log warnings to its audit log about unknown containers.  For example:

{noformat}
2013-03-06 21:04:55,327 WARN nodemanager.NMAuditLogger: USER=UnknownUser	IP=xx	OPERATION=Stop Container Request	TARGET=ContainerManagerImpl	RESULT=FAILURE	DESCRIPTION=Trying to stop unknown container!	APPID=application_1359150825713_3947178	CONTAINERID=container_1359150825713_3947178_01_001266
{noformat}

Looking closer at the audit log and the NM log shows that the container completed successfully and was forgotten by the NM before the stop request arrived.  The NM should avoid warning in these situations since this is a "normal" race condition.
