> For each SyncConnected event,  the ZooKeeperWatcher will append the session 
> id to its identity.
> During the failover of zk, the zookeeper client can connect to the zk server, 
> but the the zk server can not serve the request, so the client will try 
> continually, which will produce many SyncConnected events and a very large 
> identifier of ZooKeeperWatcher in hbase log.
