Description
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.
