Karthik Kambatla commented on YARN-2:
-------------------------------------
Sure, we can fix the nits in follow up JIRAs. I am not very particular, but the
following one comment would be nice to fix here (for fixed API), unless you
think it is not a good idea.
- Following up on earlier discussions about this, passing {{int dominance}}
instead of {{boolean dominant}} to {{#getResourceAsValue}} would address both
performance and API concerns. For now, we can check for {{(dominance == 1)}}
> Enhance CS to schedule accounting for both memory and cpu cores

> With YARN being a general purpose system, it would be useful for several
> applications (MPI et al) to specify not just memory but also CPU (cores) for
> their resource requirements. Thus, it would be useful to the
> CapacityScheduler to account for both.
