Jian He commented on YARN-1521:
-------------------------------
- we should at least log this event saying this is an earlier submitted
application, which is good for debugging.
- TestProtocolHA -> TestProtocolHABase.java
- I ran TestApplicationClientProtocolOnHA locally without core code changes,
the whole test eventually takes 15 mins to crash.
I observed that the test keeps doing failover even if the test is done. can you
investigate ?
