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

             Summary: Express Upgrade: UI - Disallow RU in HDP 2.1->2.3 since 
no upgrade pack supports it
                 Key: AMBARI-13594
                 URL: https://issues.apache.org/jira/browse/AMBARI-13594
             Project: Ambari
          Issue Type: Story
          Components: ambari-web
    Affects Versions: 2.1.3
            Reporter: Xi Wang
            Assignee: Xi Wang
             Fix For: 2.1.3


CompatibleRepositoryVersion ResourceProvider will have one more field called 
"upgrade_types" that will be a list of all of the upgrade types that are 
supported from the current stack to the target stack of the repo version that 
is registered.

E.g.,
* Current stack is 2.1
* Cluster Version record for HDP 2.3 is INSTALLED (and has  repo)

Then the button for Perform Upgrade should check the compatible repositories 
endpoint for 2.1->2.3. That particular path will only allow NON_ROLLING (aka 
Express Upgrade).
