Health checker interval does not appear to work - according to web ui
---------------------------------------------------------------------
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.
