> Key: YARN-5907
> URL: https://issues.apache.org/jira/browse/YARN-5907
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: resourcemanager
> Affects Versions: 3.0.0-alpha1
> Reporter: Steve Loughran
> Assignee: Wangda Tan
>
> 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.
