> Key: ZOOKEEPER-2257

> Project: ZooKeeper
> Issue Type: Improvement
> Reporter: Arshad Mohammad
> Assignee: Arshad Mohammad
>
> 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}
