Jian He commented on YARN-2136:
-------------------------------

On a second check, state-store is actually already stopped/closed when RM gets fenced, which means no more store operation can be performed once RM gets fenced. [~kkambatl], is this the case?

> RMStateStore can choose to handle/ignore store/update events upfront instead of invoking more ZK operations if state store is at fenced state.
