Yufei Gu created YARN-7315:
------------------------------

             Summary: Reconsider "Public" API in SchedulingPolicy of Fair Scheduler 
                 Key: YARN-7315
                 URL: https://issues.apache.org/jira/browse/YARN-7315
             Project: Hadoop YARN
          Issue Type: Bug
          Components: fairscheduler
    Affects Versions: 3.1.0
            Reporter: Yufei Gu


The original intention should be to make {{SchedulingPolicy}} Public is to let users write their own policies. However, it shouldn't work for its all methods. For example, {{isChildPolicyAllowed}} and {{checkIfUsageOverFairShare}} shouldn't be Public API. We need to reconsider if we still want {{SchedulingPolicy}} to be a public API or make it private then create interface with less methods.
