[jira] [Created] (YARN-3902) Fair scheduler preempts ApplicationMaster

He Tianyi created YARN-3902:
-------------------------------

             Summary: Fair scheduler preempts ApplicationMaster
                 Key: YARN-3902
                 URL: https://issues.apache.org/jira/browse/YARN-3902
             Project: Hadoop YARN
          Issue Type: Bug
          Components: fairscheduler
    Affects Versions: 2.3.0
         Environment: 3.16.0-0.bpo.4-amd64 #1 SMP Debian 3.16.7-ckt2-1~bpo70+1 (2014-12-08) x86_64
            Reporter: He Tianyi


YARN-2022 have fixed the similar issue related to CapacityScheduler.
However, FairScheduler still suffer, preempting AM while other normal containers running out there.

I think we should take the same approach, avoid AM being preempted unless there is no container running other than AM.
