> We should not pull in the second region server instance from zk. It is
> actually dead. We can figure this out by the hostname, and the port. We can
> assume no two region server instances can be alive on the same host, the same
> port. To be more cautious, we can check the timestamp as well. The live one
> should be that with the late timestamp, not pulled in from zk.
