Srimanth Gunturi commented on AMBARI-6088:
------------------------------------------

Good catch. This is very similar to AMBARI-3721 where memory_used_percentage 
was being calculated as _allocated/available_ instead of 
_allocated/(allocated+available)_. 

This JIRA should be fixed similarly where 
{code}
seriesData = (availableData != 0) ? (allocatedData * 100) / (availableData + 
allocatedData) : 0;
{code}

> 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.
