Killed task attempt_1373875322959_0032_m_000000_0

Observation:
===========
1. task state has been transitioned from SUCCEEDED to SCHEDULED
2. For a Succeeded attempt , when client issues Kill , then the client is notified as killed for a succeeded attempt.
3. Launched second task_attempt which is succeeded and then killed later on client request.
4. Even after the job state transitioned from SUCCEEDED to ERROR , on UI the state is succeeded

Issue :
=====
1. Client has been notified that the atttempt is killed , but acutually the attempt is succeeded and the same is displayed in JHS UI.
2. At App master InvalidStateTransitonException is thrown .
3. At client side and JHS job has exited with state Finished/succeeded ,At RM side the state is Finished/Failed.
