[jira] [Created] (YARN-482) FS: Extend SchedulingMode to intermediate queues

Karthik Kambatla created YARN-482:
-------------------------------------

             Summary: FS: Extend SchedulingMode to intermediate queues
                 Key: YARN-482
                 URL: https://issues.apache.org/jira/browse/YARN-482
             Project: Hadoop YARN
          Issue Type: Sub-task
    Affects Versions: 2.0.3-alpha
            Reporter: Karthik Kambatla
            Assignee: Karthik Kambatla


FS allows setting {{SchedulingMode}} for leaf queues. Extending this to non-leaf queues allows using different kinds of fairness: e.g., root can have three child queues - fair-mem, drf-cpu-mem, drf-cpu-disk-mem taking different number of resources into account. In turn, this allows users to decide on the scheduling latency vs sophistication of the scheduling mode.
