             Summary: Fix ratio problem on FairScheduler page
                 Key: YARN-3111
                 URL: https://issues.apache.org/jira/browse/YARN-3111
             Project: Hadoop YARN
          Issue Type: Bug
          Components: fairscheduler
    Affects Versions: 2.6.0
            Reporter: Peng Zhang
            Assignee: Peng Zhang
            Priority: Minor


Found 3 problems on FairScheduler page:
1. Only compute memory for ratio even when queue schedulingPolicy is DRF.
2. When min resources is configured larger than real resources, the steady fair 
share ratio is so long that it is out the page.
3. When cluster resources is 0(no nodemanager start), ratio is displayed as 
"NaN% used"

Attached image shows the snapshot of above problems.
