Jian He commented on YARN-1521:
-------------------------------

In TestApplicationClientProtocolOnHA , each client API call involves a new 
miniYarnCluster start and shutdown,  how long does it take for the whole test 
to finish ? If that's too long, we can just reuse one miniYarnCluster.

> Mark appropriate protocol methods with the idempotent annotation or 
> AtMostOnce annotation

> to identify whether we need to add idempotent annotation and which methods 
> can be marked as idempotent.
