[jira] [Created] (YARN-7467) FSLeafQueue unnecessarily calls
ComputeFairShares.computeShare() to calculate fair share for apps
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.
