Jian He commented on YARN-2061:
-------------------------------

Hi Ray, thanks for cleaning it up. I think  a reasonable  way is to put info 
level in unusual condition which helps debugging in most cases,  and debug 
level in usual condition which avoids excessive loggings.

> Revisit logging levels in ZKRMStateStore

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