Steve Loughran created YARN-1042: ------------------------------------ Summary: add ability to specify affinity/anti-affinity in container requests Key: YARN-1042 URL: https://issues.apache.org/jira/browse/YARN-1042 Project: Hadoop YARN Issue Type: New Feature Components: resourcemanager Affects Versions: 3.0.0 Reporter: Steve Loughran
container requests to the AM should be able to request anti-affinity to ensure that things like Region Servers don't come up on the same failure zones. Similarly, you may be able to want to specify affinity to same host or rack without specifying which specific host/rack. Example: bringing up a small giraph cluster in a large YARN cluster would benefit from having the processes in the same rack purely for bandwidth reasons. -- This message is automatically generated by JIRA.
