> 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

> clusterId=2, serviceName=KERBEROS,
> 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
