[jira] [Updated] (HBASE-3052) Add ability to have multiple ZK

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.
