[jira] [Created] (YARN-5831) Propagate allowPreemptionFrom flag all the way down to the app

Karthik Kambatla created YARN-5831:
--------------------------------------

             Summary: Propagate allowPreemptionFrom flag all the way down to the app
                 Key: YARN-5831
                 URL: https://issues.apache.org/jira/browse/YARN-5831
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: fairscheduler
            Reporter: Karthik Kambatla


FairScheduler allows disallowing preemption from a queue. When checking if preemption for an application is allowed, the new preemption code recurses all the way to the root queue to check this flag. 

Propagating this information all the way to the app will be more efficient.
