> Since the manual kerb option requires users to run the wizard, get the csv, and potentially
(likely) exit and return once their kerb infra is ready, this is a situation users will run
into...
> 1) start kerb wizard, choose manual option
> 2) get to page with csv, download, exit wizard
> 3) even though kerb is not enabled, kerberos service has now been added to the cluster
but with 0 clients install (see attached screen shot).
> 4) if i attempt to do bulk start commands (for example), things fail silently...for example:
i went "Start All" from the Actions menu and nothing happened. went to firebug and see the
API command had failed with a 500.

>   "message" : "org.apache.ambari.server.controller.spi.SystemException: An internal system
exception

>  currentDesiredState=INIT, newDesiredState=STARTED"
> }
> {code}
> *Cause*
> When transitioning from the _Configure Kerberos_ page to the _Configure Identities_ (Skipping
the _Install and Test Kerberos Client_ page), the KERBEROS service is added to the cluster
and the KERBEROS_CLIENT component  is added to each host. The service and components are the
INIT state at this point. After proceeding to the _Confirm Configuration_ page and then exiting,
the KERBEROS service is not cleaned up, leaving it and it's components in the INIT state.

> *Side-effect*
> The user sees that the Kerberos service in the list of installed services even though
the Kerberization process was not completed
