Vinod Kumar Vavilapalli commented on MAPREDUCE-4748:
----------------------------------------------------
Genuine bug. TaskImpl needs to accept T_ATTEMPT_SUCCEEDED at SUCCEEDED. Not
sure how we missed something as basic as this. We should also accept-and-ignore
T_KILL and T_ATTEMPT_COMMIT_PENDING.

> like this is an error in the state machine either between the task attempts
