> The web client currently uses a combination of host names, host_state, and
> stack versions to determine if an upgrade should be able to be performed for
> a given stack. If any of the hosts are missing the correct stack, then the
> option to upgrade to that stack is not permitted. The upgrade should be
> allowed, however, if the hosts which are missing the required stack are also
> in maintenance mode.
> The web client should begin using the prerequisite check API endpoint in
> order to calculate if the "Upgrade" button is to be visible for a specific
> stack. This allows the logic for calculating whether at stack is ready
> upgrade to remain on the Ambari Server.
