If you have exited out of the Enable Kerberos Wizard, make sure all services are shut down (according to Ambari). Then take a look at master01.deepscale.com to see if the Zookeeper Server instance on there has shut down. Once Zookeeper has been confirmed to have been shutdown, try to start Zookeeper using Ambari. If it comes up, use Ambari to execute the Zookeeper service check.

If the Zookeeper server does not start up, take a look at the log (/var/log/zookeeper/zookeeper.out) and see if there are any interesting errors in there. Additionally, you can attach the log file to this question so we can take a look. Maybe there is something wrong with the Zookeeper Kerberos Identity.

I am not sure what the issue could be. I just walked through this on a local cluster and it worked smoothly for me.

Maybe try to disable Kerberos, make sure all starts up ok, then re-enabled Kerberos.
