Hitesh Shah commented on MAPREDUCE-3888:
----------------------------------------
Actually, given that now we have the container.pid files, we should be to kill
containers from the earlier NM instance too. Will file a separate jira to kill
running containers both on an NM shutdown as well on startup ( for unclean
shutdowns ).
> Ensure/confirm that the NodeManager cleanup their local filesystem when they
> restart
