----------------------------------
Thanks [~ywskycn], in general the patch looks good to me. And could you open a
follow up JIRA to track documentation changes (or add them to the same JIRA if
you like). Now we have 3 knobs to control #containers allocated for each node
heartbeat. It's better to clearly document them.
> Capacity Scheduler : Assign single or multiple containers per heart beat
> driven by configuration

> 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.
