Jian He commented on YARN-659:
------------------------------
Hi [~ozawa], I noticed that while we are removing app state from ZK, we still
need to know the associated attempt IDs ? And remove app and attempts as a
multi operation. If ZK supports 'directory removal', then we are fine, simply
removing the app root dir and all the sudir's attempts are gone. But if not,
removeApplication APIs can not just take an applicationId, we can close this
ticket in this case.
> RMStateStore's removeApplication APIs should just take an applicationId

> There is no need to give in the whole state for removal - just an ID should
> be enough when an app finishes.
