Karthik Kambatla resolved MAPREDUCE-5718.
-----------------------------------------
Resolution: Won't Fix
Target Version/s: (was: )
With work-preserving RM/NM restart, one can run into this only when the AM dies
or the node running the AM dies. This is no longer a regression when moving
from MR1 to MR2.
Closing this as "Won't Fix" for now. Please re-open if needed.
> MR AM should tolerate RM restart/failover during commit
