Jian He commented on YARN-2136:
-------------------------------
bq. Hence dispatcher queue draining shouldn't matter as ZKClient is already closed.
After checking the code, I think we should flip the order "closeInternal()" and "dispatcher.stop();"
right?
{code}
protected void serviceStop() throws Exception {
closeInternal();
dispatcher.stop();
}
{code}
> RMStateStore can explicitly handle store/update events when fenced

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