Vinod Kumar Vavilapalli commented on MAPREDUCE-3031:
----------------------------------------------------

+1, lgtm.

There are a couple of missing transitions on ContainerState.LOCALIZATION_FAILED, not really
caused by/part of this patch. Will track them separately.

> Started a cluster. Submitted a sleep job with around 10000 maps and 1000 reduces.
> Killed AM with kill -9 by which time already 7000 thousands maps got completed.
> On the RM webUI, Application is stuck in Application.RUNNING state. And JobClient goes
into an infinite loop as RM keeps telling the client that the application is running.
