    [ https://issues.apache.org/jira/browse/ZOOKEEPER-2257?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15786468#comment-15786468

Rajesh Chandramohan commented on ZOOKEEPER-2257:
------------------------------------------------

We have a related issue, Where our Zookeeper service is running as hadoop/hostname principle.
But ZkClient default use server principle as zookeeper/hostname@REALM . How do we change to
use hadoop/hostname@REALM  ?

> Make zookeeper server principal configurable at zookeeper client side

> 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}
