Karthik Kambatla commented on YARN-326:
---------------------------------------
Neatly done, Sandy. I have one comment: given we have ResourceType now, it
might be better to get rid of memory/cpu specific methods in ResourceWeights.
The following two methods should suffice.
{code}
float getWeight(ResourceType rt);
void setWeight(ResourceType rt, float weight);
{code}
> Add multi-resource scheduling to the fair scheduler

> With YARN-2 in, the capacity scheduler has the ability to schedule based on
> multiple resources, using dominant resource fairness. The fair scheduler
> should be able to do multiple resource scheduling as well, also using
> dominant resource fairness.
> More details to come on how the corner cases with fair scheduler configs such
> as min and max resources will be handled.
