Arun C Murthy updated MAPREDUCE-4327:
-------------------------------------
Attachment: MAPREDUCE-4327.patch
Initial (incomplete) sketch of DRF for YARN CS... hopefully this provides
enough context for folks to get an good feel.
Essentially I've added the ability for applications to ask for cores alongwith
memory and a configurable resource-comparator for the CS to implement DRF-like
multi-resource scheduling.
Thoughts?
> 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.
