Jason Lowe updated YARN-1362:
-----------------------------
Attachment: YARN-1362.patch
Small patch that enhances the NM context that provides get/set for a decomm
flag. This allows code to query whether the NM has been told to decommission
and act accordingly during shutdown.
> Distinguish between nodemanager shutdown for decommission vs shutdown for
> restart

>
> When a nodemanager shuts down it needs to determine if it is likely to be
> restarted. If a restart is likely then it needs to preserve container
> directories, logs, distributed cache entries, etc. If it is being shutdown
> more permanently (e.g.: like a decommission) then the nodemanager should
> cleanup directories and logs.
