------------------------------------
Resolution: Duplicate
> 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: 2.0.3-alpha, 0.23.6
> Reporter: Jason Lowe
> Assignee: Omkar Vinit Joshi
>
> 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.
