Bikas Saha updated MAPREDUCE-3921:
----------------------------------
Attachment: MAPREDUCE-3921-9.patch
Adding patch in which AM sends kill event to map and reduce tasks to keep
behavior similar to JT in mrv1.
Thing to note, is that the RM also terminates such containers. However, in AM
such RM terminations mark the task attempt as FAILED but in this case we need
to mark them as KILLED. So it is necessary to send the kill event in the AM so
that it pre-empts the state transition to FAILED in the normal handling of such
cases.
> MR AM should act on the nodes liveliness information when nodes go
> up/down/unhealthy
