Master Service fails to tolerate faults when zookeepr recovers:
When the zookeepr service is shut down（bin/zkServer.sh stop）, the master
will throw a message indicating that the connection to zookeepr times out.
```
org.apache.zookeeper.ClientCnxn$EndOfStreamException: Unable to read
additional data from server sessionid 0x1005793a4050000, likely server has
closed socket

```
When zookeepr is recovers, the master service is stopped due to a fault
recovery failure.
