----------------------------------------

             Summary: Stop-and-Start Upgrade: API to show available Upgrade options from Current
stack to Desired stack
                 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.
