William W. Graham Jr created YARN-10302:
-------------------------------------------

             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.
