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
Reporter: Vinod Kumar Vavilapalli
Assignee: Vinod Kumar Vavilapalli
Priority: Blocker
Fix For: 0.23.0
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.
