> NM should act on a REBOOT command from RM
> -----------------------------------------

> Key: MAPREDUCE-3034
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3034
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2, nodemanager
> Affects Versions: 0.23.0, 0.24.0
> Reporter: Vinod Kumar Vavilapalli
> Assignee: Devaraj K
> Attachments: MAPREDUCE-3034.patch, MR-3034.txt

>
> RM sends a reboot command to NM in some cases, like when it gets lost and
> rejoins back. In such a case, NM should act on the command and
> reboot/reinitalize itself.
> This is akin to TT reinitialize on order from JT. We will need to shutdown
> all the services properly and reinitialize - this should automatically take
> care of killing of containers, cleaning up local temporary files etc.
