Bikas Saha commented on TEZ-2379:
---------------------------------
Please see analysis above. It should actually be invalid for an attempt killed
to come after the task state is killed because the task is supposed to wait for
attempts to be complete before entering a final state - thats the whole point
of the kill_wait state, right?
IMO, the fix is to have the attempt ignore a kill request if its already done.
Thoughts?
