Liyin Tang updated HBASE-3052:
------------------------------

    Attachment: HBASE_3052[r1083993].patch

This is my HBase Hackthon project.
Now the MiniZooKeeperCluster can have multiple ZK servers. And the client can kill the current
ZK and start another candiate ZK.

> Interesting things can happen when you have a ZK quorum of multiple servers and one of
them dies.  Doing testing here on clusters, this has turned up some bugs with HBase interaction
with ZK.
> Would be good to add the ability to have multiple ZK servers in unit tests and be able
to kill them individually.
