Yun Zhao commented on HBASE-19925:
----------------------------------
[~yuzhih...@gmail.com]
It is really because of this.
However, when the ReplicationSource terminating, Should not start a new
ReplicationSourceWorkerThread / ReplicationSourceShipper thread.
And this thread will reconnect zookeeeper, Cause zookeeper SendThread can not
stop.
> Delete an unreachable peer will triggers all regionservers abort
