Jason Lowe resolved YARN-3096.
------------------------------
Resolution: Invalid
The user interface still shows 100% because the wrong property is being set, so
the queue is not using a 25% user limit. This can also be verified by
examining the RM logs after it starts up or the queues are refreshed.
In queue properties the queue name needs to be the full path including "root",
so the property should be
yarn.scheduler.capacity.root.default.miminum-user-limit-percent. See the
[CapacityScheduler
documentation|http://hadoop.apache.org/docs/r2.6.0/hadoop-yarn/hadoop-yarn-site/CapacityScheduler.html]
for more details.

> Project: Hadoop YARN
> Issue Type: Bug

> Affects Versions: 2.6.0
> Environment: HDP 2.2 with RM HA & Kerberos managed by Ambari 1.7
> Reporter: Hari Sekhon
> Attachments: screenshot-1.png

>
> After setting the Capacity Scheduler minimum-user-limit-percent to 25 it
> still shows as 100% in the RM web UI under Scheduler even after doing queue
> refresh and even fully restarting both HA Resource Managers.
> /etc/hadoop/conf/capacity-scheduler.xml:
> {code}<configuration>
> <property>
> <name>yarn.scheduler.capacity.default.minimum-user-limit-percent</name>
> <value>25</value>
> </property>
> ...{code}
> This cluster is Kerberized and managed by Ambari, I've refreshed via both
> Ambari and manually on the command line via
> {code}yarn rmadmin -refreshQueues{code}
> but it still shows the same.
> Screenshot attached to show it still shows 100% instead of the expected 25%.
