bq.Yes. so you ok with existing two config fields?
Yes. We can do two configs. Any other options with one config param may confuse
user more.
bq.Yes, now checking is little confused. I refactored to more clearer.
Makes sene
bq.For now, I more prefer to do it in scheduler-level
Lets do this at scheduler level for now. I think we can extend to queue level a
little later when its really needed. Else it may complicate a little more.

> Capacity Scheduler right now schedules multiple containers per heart beat if
> there are more resources available in the node.
> This approach works fine however in some cases its not distribute the load
> across the cluster hence throughput of the cluster suffers. I am adding
> feature to drive that using configuration by that we can control the number
> of containers assigned per heart beat.
