Vinod Kumar Vavilapalli commented on MAPREDUCE-3054:
----------------------------------------------------
That's a little different. Cleaning up of containers(or AM)' process tree is
independent and can be triggered once it is clear for the components in
question that they are done with their work - via TaskUmbilicalProtocol.done()
for the task and AMRMProtocol.unregister() for the AM case.
For the killed jobs, once AM gets the kill-signal, it can gracefully shut down
by writing history-file, sending notification url etc, then it can proceed to
deregistering with the RM. Once the deregistration comes through, the RM can
then direct the NM to make sure the AM is dead.
