Subject [jira] [Commented] (YARN-2143) Merge common killContainer logic of Fair/Capacity scheduler into AbstractYarnScheduler
Date Tue, 24 Jun 2014 15:28:25 GMT

Wangda Tan commented on YARN-2143:
----------------------------------

Hi Sunil,
Thanks for your comment, I took a look at FairScheduler/CapacityScheduler again, I think completedContainer
looks more like what we need put in AbstractYarnScheduler. Both of warnOrKillContainer and
killContainer invokes completedContainer.
This issue is created because of YARN-1408, I feel we'd better leave this alone here and wait
for some feedbacks from community, we can add ResourceRequest logic separately in Fair/CapacityScheduler
for now, and refactor it in the future.
Thanks,

> Currently, CapacityScheduler has killContainer API inherited from PreemptableResourceScheduler,
and FairScheduler uses warnOrKillContainer to do container preemption. We'd better to merge
common code to kill container into AbstractYarnScheduler.
