Tsuyoshi OZAWA commented on YARN-2061:
--------------------------------------

The logging in 
removeRMDelegationTokenState()/updateRMDelegationTokenAndSequenceNumberInternal()/removeRMDTMasterKeyState()
 can be for RACE and DEBUG levels.

{code}
LOG.info("Done Loading applications from ZK state store");
{code}
About this log, how about moving this to the tail of loadRMAppState()?

> ZKRMStateStore has a few places where it is logging at the INFO level. We 
> should change these to DEBUG or TRACE level messages.
