Wangda Tan commented on YARN-1651:
----------------------------------
[~mding], I think for your last example, if RM decides to rollback resources,
it should send a container decrease event to NM as well, NM can ignore the
decrease event if target size of container is equals to existing container
size. Sounds like a plan?
> CapacityScheduler side changes to support increase/decrease container
> resource.
