https://github.com/apache/hadoop/pull/2044
> Support custom packing algorithm for FairScheduler
> --------------------------------------------------
>
> Key: YARN-10302
> URL: https://issues.apache.org/jira/browse/YARN-10302
> Project: Hadoop YARN
> Issue Type: New Feature
> Reporter: William W. Graham Jr
> Priority: Major
>
> The {{FairScheduler}} class allocates containers to nodes based on the node
> with the most available memory[0]. Create the ability to instead configure a
> custom packing algorithm with different logic. For instance for effective
> auto scaling, a bin packing algorithm might be a better choice.
