Hars Vardhan commented on AMBARI-6088:
--------------------------------------
So, I propose two ways to make this metric widget useful:
1. Use absolute memory used by each queue (MB/GB/TB).
2. Use Yarn.maxMemory to get Absolute Used Capacity (%).
Can somebody let me know the design purpose of this metric widget on YARN
summary page?
Which of the above is better for its usability?
> Ambari-web's YARN Metric "Queue Memory Used" is not meaningful

> Key: AMBARI-6088
> URL: https://issues.apache.org/jira/browse/AMBARI-6088
> Project: Ambari
> Issue Type: Bug
> Affects Versions: 1.5.1, 1.6.0, 1.6.1
> Reporter: Hars Vardhan
>
> 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.
