Description

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.,

    <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>
