> Key: AMBARI-13556
> URL: https://issues.apache.org/jira/browse/AMBARI-13556
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.2.0, 2.1.3
> Reporter: Swapan Shridhar
> Assignee: Swapan Shridhar
> Priority: Critical
> Fix For: 2.2.0, 2.1.3
>
>
> For most cases, UI will allow both RU and EU.
> However, for HDP 2.1->2.3, only EU is supported, this means we cannot show
> the button for RU. Hence, the UI has to either remove/disable the RU option.
> We need an API to find out which upgrade types are valid given the current
> stack and desired stack.
