> Server principal on client side is derived using hostname.
> org.apache.zookeeper.ClientCnxn.SendThread.startConnect()
> {code}
>            try {
>                 zooKeeperSaslClient = new ZooKeeperSaslClient("zookeeper/"+addr.getHostName());
>             }
> {code}
> This may have problems when admin wanted some customized principals like zookeeper/clusterid@HADOOP.COM
where clusterid is the cluster identifier but not the host name.
> IMO, server principal also should be configurable as hadoop is doing.
