             Summary: Make scheduling mode in FS pluggable
                 Key: YARN-469
                 URL: https://issues.apache.org/jira/browse/YARN-469
             Project: Hadoop YARN
          Issue Type: Sub-task
    Affects Versions: 2.0.3-alpha
            Reporter: Karthik Kambatla
            Assignee: Karthik Kambatla


Currently, scheduling mode in FS is limited to Fair and FIFO. The code typically has an if condition at multiple places to determine the correct course of action.

Making the scheduling mode pluggable helps in simplifying this process, particularly as we add new modes (DRF in this case).
