> Upgraded Ambari Server from 2.1.2.1 to 2.2.1.
> capacity-scheduler.xml prior to upgrade intentionally did not have the
> default queue (per the customer's requirement).
> Ambari automatically added the following, which is unwanted:
> {noformat}
> yarn.scheduler.capacity.default.minimum-user-limit-percent=100
> yarn.scheduler.capacity.root.default.acl_administer_jobs=*
> yarn.scheduler.capacity.root.default.acl_submit_applications=*
> yarn.scheduler.capacity.root.default.capacity=100
> yarn.scheduler.capacity.root.default.maximum-capacity=100
> yarn.scheduler.capacity.root.default.state=RUNNING
> yarn.scheduler.capacity.root.default.user-limit-factor=1
> {noformat}
> This is probably because Ambari Server on upgrade adds default properties
> that are missing from the existing configs.
