Subject [jira] [Created] (YARN-7467) FSLeafQueue unnecessarily calls ComputeFairShares.computeShare() to calculate fair share for apps
Date Thu, 09 Nov 2017 18:37:00 GMT
Daniel Templeton created YARN-7467:
--------------------------------------

             Summary: FSLeafQueue unnecessarily calls ComputeFairShares.computeShare() to
calculate fair share for apps
                 Key: YARN-7467
                 URL: https://issues.apache.org/jira/browse/YARN-7467
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: fairscheduler
    Affects Versions: 3.1.0
            Reporter: Daniel Templeton
            Priority: Critical


All apps have the same weight, the same max share (unbounded), and the same min share (none).
 There's no reason to call {{computeShares()}} at all.  Just divide the resources by the number
of apps.
