Sunil G commented on YARN-4161: ------------------------------- Thanks [~ywskycn] for rebasing the patch. Few high level comments # Could you please name patch to something like YARN-4161.002.patch etc by following the naming convention. It will be more easier. # I thoughts we can rename the configuration to "yarn.scheduler.capacity.per-node-heartbeat.maximum-container-assignments". More thoughts are welcome # Once 2 is confirmed, rename all variables and getters/setter in align with config name # I prefer not to have a config like "yarn.scheduler.capacity.assignmultiple". If we can make the default of "yarn.scheduler.capacity.per-node-heartbeat.maximum-container-assignments" to -1, we can assume the feature is off and we can continue allocate any numbers of containers as possible in a heartbeat. Once configured, we can assume that feature is on and restrict as per the limit imposed. > 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: capacity scheduler > Reporter: Mayank Bansal > Assignee: Mayank Bansal > Labels: oct16-medium > Attachments: YARN-4161.patch, YARN-4161.patch.1 > > > 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.
