Summary: 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
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.
