Laxman created ZOOKEEPER-1467:
---------------------------------

             Summary: Server principal on client side is derived using hostname.
                 Key: ZOOKEEPER-1467
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1467
             Project: ZooKeeper
          Issue Type: Bug
          Components: java client
    Affects Versions: 3.4.3, 3.4.4, 3.5.0, 4.0.0
            Reporter: Laxman
            Priority: Blocker


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/[email protected] where clusterid is the cluster identifier but 
not the host name.

IMO, server principal also should be configurable as hadoop is doing.
