Alejandro Abdelnur commented on YARN-1042: ------------------------------------------ it seems much of this could be achieved via YARN-796 > 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.
