>          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.
