Description

After adding a new stack version to Ambari and selecting it to be installed on a specific cluster, the UI changes to the cluster versions page. If the upgrade path (aka the upgrade pack) is not available for the transition from the current stack version to the new stack version then the selected version is not seen on that next screen. This transition is silent leaving the user confused as to where the version went.
For example: Adding HDP 2.5 to a cluster where the current stack is HDP 2.2.
