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

             Summary: EU: Downgrade goes through all steps even if initiated at first prompt, should exit since hasn't changed stack/configs
                 Key: AMBARI-14238
                 URL: https://issues.apache.org/jira/browse/AMBARI-14238
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.2.0
            Reporter: Dmytro Grinenko
            Priority: Critical
             Fix For: 2.2.0


Steps:
1. Setup HDP 2.3.2 cluster with Ambari 2.1.3
2. Initiate Express Upgrade
3. Wait for the first message titled "stop all YARN queues" to appear
4. Hit Downgrade
Result:
Downgrade starts all the way from top as if it was triggered at Finalize HDFS phase and takes a while to complete
Expected Result:
It would be good to have downgrade attempt the actions only for which downgrade is really required
