> Upgrading to 2.5.1 after a fresh install of HDP-2.6 using 2.5.0.3, adds
> cgroup configs and results in YARN restart required indicator.

> This is because https://issues.apache.org/jira/browse/AMBARI-19311 added the
> logic to remove these configs when cgroup is not enabled but as the config
> properties have {{<on-ambari-upgrade add="true"/>}} they get auto added when
> Ambari is upgraded.
> I believe simply setting {{<on-ambari-upgrade add="true"/>}} to
> {{<on-ambari-upgrade add="false"/>}} will fix this issue.
