Liyin Tang updated HBASE-3052:
------------------------------
Attachment: HBASE_3052[r1084033].patch
I attached a new patch: HBASE_3052[r1084033].patch here.
In this patch, the miniZKCluster will start to run multiple ZK servers
together. One of them is the current active one, others are the backup ZK
servers.
So the client can killCurrentActiveZooKeeperServer or
killOneBackupZooKeeperServer.
When calling killCurrentActiveZooKeeperServer, it will return next available
backup ZooKeeper servers to client. If no more backups, return -1;
When calling killOneBackupZooKeeperServer, it will kill one backup if there are
backups.
> Add ability to have multiple ZK servers in a quorum in MiniZooKeeperCluster
> for test writing

> 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.
