Varun Saxena commented on YARN-5903:
------------------------------------
[~haibochen], previously we were throwing IOException if RM did not change to
STARTED state.
So shouldn't we check result of CountDownLatch#await and if its false, throw an
IOException as that will indicate RM has not yet started.

> resourcemanager.getServiceState() == STATE.STARTED does not guarantee
> resource manager is fully started.
