-----------------------------------------------
Is this really a duplicate? Is it something that should be resolved before 3.5.5 releases?

> 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.
