[jira] [Created] (YARN-6307) Refactor FairShareComparator#compare

Yufei Gu created YARN-6307:
------------------------------

             Summary: Refactor FairShareComparator#compare
                 Key: YARN-6307
                 URL: https://issues.apache.org/jira/browse/YARN-6307
             Project: Hadoop YARN
          Issue Type: Bug
          Components: fairscheduler
            Reporter: Yufei Gu
            Assignee: Yufei Gu


The method did three things: check the min share ratio, check weight ratio, break tied by submit time and name. They are mixed with each other which is not easy to read and maintenance,  poor style. Additionally, there are potential performance issues, like no need to calculate weight ratio every time.
