> 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.
