Subject [jira] [Created] (YARN-6828) [Umbrella] Container preemption using OPPORTUNISTIC containers
Date Sat, 15 Jul 2017 16:49:00 GMT
Arun Suresh created YARN-6828:
---------------------------------

             Summary: [Umbrella] Container preemption using OPPORTUNISTIC containers
                 Key: YARN-6828
                 URL: https://issues.apache.org/jira/browse/YARN-6828
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Arun Suresh
            Assignee: Arun Suresh


Currently, the YARN schedulers selects containers for preemption only in response to a starved
queue / app's request. We propose to allow the Schedulers to mark containers that are allocated
over queue capacity/fair-share as Opportunistic containers.
