[jira] [Created] (AMBARI-10833) Yarn scheduler changes should not prompt Resource Manager restarts now that Scheduler Refresh is available

Hari Sekhon created AMBARI-10833:
------------------------------------

             Summary: Yarn scheduler changes should not prompt Resource Manager restarts now that Scheduler Refresh is available
                 Key: AMBARI-10833
                 URL: https://issues.apache.org/jira/browse/AMBARI-10833
             Project: Ambari
          Issue Type: Improvement
          Components: ambari-server
    Affects Versions: 2.0.0
         Environment: HDP 2.2
            Reporter: Hari Sekhon
            Priority: Trivial


Ambari has had Yarn Scheducler Refresh capability for a little while now since 1.7 (AMBARI-5937) but it still prompts users to restart Yarn Resource Managers which is unnecessary.

It should instead prompt users via the message above config to run a Scheduler Refresh. After a Scheduler Refresh the prompt for restarting the Resource Managers goes away, but less experienced users could end up often needlessly rebooting their Resource Managers due to this message.
