> Key: MAPREDUCE-3637
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3637
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.0
> Reporter: Thomas Graves
> Priority: Critical
>
> 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.
