-----------------------------------

             Summary: Used queue percentage not accurate in UI for 2.7 and 
below when using DominantResourceCalculator
                 Key: YARN-6152
                 URL: https://issues.apache.org/jira/browse/YARN-6152
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Jonathan Hung
            Assignee: Jonathan Hung


YARN-4751 adds the {{getUsedCapacity}} and {{getAbsoluteUsedCapacity}} methods 
to {{AbstractCSQueue}} which is used to display queue usage in UI for 
branch-2.7 and below. However if there is more than one partition in the 
cluster, with different dominant resources, then queue usage may not be 
displayed as expected.

Contrived example: Default partition has <90GB, 10vcores>, and "test" partition 
has <10GB, 90vcores>. {{root}} queue in default partition uses <50GB, 
10vcores>. Here we expect queue usage to be 100 since it is using all vcores in 
default partition. But the displayed usage will be (50GB/100GB)/(90GB/100GB) = 
55.6%.
