Mahadev konar commented on MAPREDUCE-2892:
------------------------------------------
@Vinod,
I think the final state should not be a blob. There are only a few final
states that an application can get to - FAILED/SUCCESS/KILLED. Strings/binary
blob would be confusing.

> Some api changes before we declare yarn apis as stable:
> # FinishApplicationMasterRequest doesn't need to send out 'tracking url'.
> # FinishApplicationMasterRequest shouldn't use 'string' as final state - it's
> got to be an enum and we need to use that enum appropriately in the RM's
> state-machines.
