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

             Summary: EU to message users to start YARN queues if work preserving recovery
is disabled
                 Key: AMBARI-19006
                 URL: https://issues.apache.org/jira/browse/AMBARI-19006
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.5.0
            Reporter: Alejandro Fernandez
            Assignee: Alejandro Fernandez
             Fix For: 2.5.0


Today, the Express Upgrade packs message users to stop YARN queues if they do not have work
preserving recovery enabled.
However, there's no message reminding users to enable it again.

E.g.,
{code}
    <group xsi:type="cluster" name="START_YARN_QUEUES" title="Start YARN Queues 2">
      <service-check>false</service-check>
      <skippable>true</skippable>
      <parallel-scheduler/>

      <execute-stage service="YARN" component="RESOURCEMANAGER" title="Start YARN Queues">
        <condition xsi:type="config" type="yarn-site" property="yarn.resourcemanager.work-preserving-recovery.enabled"
value="true" comparison="not-equal"/>
        <task xsi:type="manual">
          <message>Before continuing, please start all YARN queues if you stopped them
in a previous step.</message>
        </task>
      </execute-stage>
    </group>
{code}
