> EventThread in ClientCnxn can't be closed when SendThread exits because of auth failed
during reconnection.
> for send thread if it is in authfailed state, the send thread exits,but the event thread
is still running.
> observation:
> use jstack tho check the thread running they find the send thread no longer exists but
event thread is still threre
> even when we call zookeeper.close(),the eventthread is still there.
