Vinod Kumar Vavilapalli updated MAPREDUCE-3034:
-----------------------------------------------
Fix Version/s: 0.23.2
Target Version/s: 0.23.2 (was: 0.23.2, 0.24.0, 0.23.0)
Affects Version/s: (was: 0.23.2)
(was: 0.24.0)
Status: Open (was: Patch Available)
Looked through the patch, fine overall.
Making trivial edit like adding comments to the code, renaming a few fields
etc. Also we don't need to make changes to CompositeService, we just need to
remove the previous shut-down hook, doing this too.
Also the fact that we are creating a new NodeManager underneath when RM asks to
reboot is a problem. This issue is because we cannot reinit a Service, will
file a separate ticket.
> NM should act on a REBOOT command from RM

> 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.
