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

             Summary: Use node label reosurce as  denominator to decide which resource is dominated
                 Key: YARN-11082
                 URL: https://issues.apache.org/jira/browse/YARN-11082
             Project: Hadoop YARN
          Issue Type: Bug
          Components: capacity scheduler
    Affects Versions: 3.1.1
            Reporter: Bo Li


We ued cluster resource as denominator to decide which resoure is dominated in AbstrctQueue#canAssignToThisQueue. Howere nodes in our cluster are configed differently.

We can find out that even thouth root.a.a1.a2 used 687/687 vcores, but the following code in AbstrctQueue#canAssignToThisQueue still return false
```java
Resources.greaterThanOrEqual(resourceCalculator, clusterResource,
          usedExceptKillable, currentLimitResource)
```
 clusterResource = <memory:175117312, vCores:40222>
usedExceptKillable = <memory:3381248, vCores:687> 
currentLimitResource = <memory:3420315, vCores:687>

currentLimitResource:
memory : 3381248/175117312 = 0.01930847362
vCores : 687/40222 = 0.01708020486

usedExceptKillable:
memory : 3384320/175117312 = 0.01932601615
vCores : 688/40222 = 0.01710506687

DRF will think memory is dominated resource and return false in this scenario
