> Affects Versions: 2.1.3

> At a high-level we may follow this approach:
> Ensure cluster is not kerberized
> Assume all services to be stopped (add a check to ensure that services are
> stopped)
> We may also need to check and confirm that there are no commands pending
> execution - or just mark them as aborted
> Update all host names in the database based on the mapping provided (e.g.
> host1 --> master01.dev.com)
> As SQLClient cannot be assumed consider using jdbc - similar to the Upgrade
> code
> Modify all configs to replace the hostnames as needed (not sure if plain
> search and replace will suffice)
> Agents need to be re-configured if ambari-server hostname changes
