[jira] [Created] (TEZ-2487) Scheduler should be able to preempt tasks instead of containers

-----------------------------------

             Summary: Scheduler should be able to preempt tasks instead of containers
                 Key: TEZ-2487
                 URL: https://issues.apache.org/jira/browse/TEZ-2487
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Siddharth Seth
            Assignee: Siddharth Seth


The scheduler currently preempts containers since task level preemption was not supported. There's changes in TEZ-2003 which allow tasks to be killed. Adding support in the AM would be useful so that containers can be re-used even if a running task needs to be preempted.

Assigning to myself for now. If anyone wants to take it over, please ping.
