Zhijie Shen commented on AMBARI-6088:
-------------------------------------
[~hars.vardhan], right! I missed the point that CS allows to go beyond the
absolute capacity. Then, we have to use absolute capacity as you suggested. The
question is what information "Queue Memory Used" wants to convey? The metric
can go beyond 100%, which means used queue memory is more than the absolute
capacity. [~srimanth.gunturi], does this make sense to Ambari users?
> Ambari-web's YARN Metric "Queue Memory Used" is not meaningful

> On this webUI : http://<ambari-host-name>:8080/#/main/services/YARN/summary
> "Queue Memory Used" graph in Ambari' YARN web page seems abnormal. Sometimes,
> queue is using more than 400% of the cluster memory!! How this is calculated?
> It doesn't match with any metrics shown on Resource Manager UI page.
