Xuan Gong commented on YARN-1521:
---------------------------------
bq. 1. If the application is already in the RM cache, we shouldn't log success.
Otherwise, there may be multiple logs for one submission.
Removed
bq. Should it sleep a while before retry?
DONE
bq. Again, sleep 1ms before next try, yielding to the thread of API methods'
invoking. And, have max retry when exception?
DONE. Did not add max retry. The failover thread will be killed after every
testcases
> Mark appropriate protocol methods with the idempotent annotation or
> AtMostOnce annotation
