> Currently Zookeeper client expects zookeeper server's principal to be in the form of zookeeper.sasl.client.username/server-ip  for example zookeeper/192.162.1.100. 
> But this may not always be the case server principal can be some thing like zookeeper/hadoop.foo.com
> It would be better if we can make server principal configurable.
> Current Code:
> {code}
> String principalUserName = System.getProperty(ZK_SASL_CLIENT_USERNAME, "zookeeper");
> zooKeeperSaslClient = new ZooKeeperSaslClient(principalUserName + "/" + addr.getHostString());
> {code}
> Proposed Code:
> {code}
> String serverPrincipal = System.getProperty("zookeeper.server.principal");
> if (null != serverPrincipal) {
>     zooKeeperSaslClient = new ZooKeeperSaslClient(serverPrincipal);
> } else {
>     String principalUserName = System.getProperty(ZK_SASL_CLIENT_USERNAME, "zookeeper");
>     zooKeeperSaslClient = new ZooKeeperSaslClient(principalUserName + "/" + addr.getHostString());
> }
> {code}
