> Key: SPARK-28022
> URL: https://issues.apache.org/jira/browse/SPARK-28022
> Project: Spark
> Issue Type: New Feature
> Components: Kubernetes
> Affects Versions: 2.4.3
> Reporter: Henry Yu
> Priority: Major
>
> Hi, in order to achieve cloud native friendly autoscaling , I propose to add a pod affinity feature.
> Traditionally, when we use spark in fix size yarn cluster, it make sense to spread containers to every node.
> Coming to cloud native resource manage, we want to release node when we don't need it any more.
> Pod affinity feature counts to place all pods of certain application to some nodes instead of all nodes.
> By the way, we can not use pod template to achieve this, for we must add application id to affinity term .
