Vinod Kumar Vavilapalli commented on MAPREDUCE-2954:
----------------------------------------------------
Because of this, the (only) MR AM had one of its map stuck in
SUCCESS_CONTAINER_CLEANUP state. On the NM, the _stopContainer()_ request from
this AM was stuck on ApplicationAttemptId too.

So because of this, the map got stuck, all the reducers were spinning for
TaskCompletionEvents and the world came to a halt.
