winghc commented on YARN-4161:
------------------------------
we just encountered this problem when we submit large job in our production
env. using ambari, which only support capacity scheduler. Any patch there?
> Capacity Scheduler : Assign single or multiple containers per heart beat
> driven by configuration
> ------------------------------------------------------------------------------------------------

> Key: YARN-4161
> URL: https://issues.apache.org/jira/browse/YARN-4161
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: capacityscheduler
> Reporter: Mayank Bansal
> Assignee: Mayank Bansal

> 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.
