      Description

      reported by QE, I think this is probably a web ui not updating issue, but not positive.

      1. The property yarn.nodemanager.health-checker.interval-ms on the RM and the DN are set to 135000 ms, or 2 minutes and
      15 sec.

      $ grep -A 2 "health-checker.interval-ms" yarn-site.xml
      <name>yarn.nodemanager.health-checker.interval-ms</name>
      <value>135000</value>
      </property>

      2. According to the web ui (e.g http://rm:8088/cluster/nodes), the 'last health-update'
      column does not get updated, except when the RM is restated.
