Mahadev konar commented on ZOOKEEPER-1467:
------------------------------------------

Agree with Laxman here. I think we need to get rid of our system properties and should not be using it for configuration. Can we use the ZK config file?

>                 zooKeeperSaslClient = new ZooKeeperSaslClient("zookeeper/"+addr.getHostName());
>             }

> 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.
