> The purpose of this Epic is to track the work required for offline upgrades.  The general workflow will be:
> * Create a host (VM) that is NOT part of a cluster that duplicates the hostname.
> * Install bits for an upgraded version of the software on a cluster.
> * Make Ambari aware that a new version is installed on the cluster.
> * Host-by-host, instruct Ambari to stop services for a host.
> * Once the components are stopped, stop the agent on the host.
> * After removing the host from the cluster, bring up the new host with the new bits pre-installed.
> * Ambari should accept the versions reported by the new host.
