-------------------------------------
I'm removing the target version, since it's trivial and we won't merge it to
2.4.
> [K8S] Split out node selector config between driver and executors.
> ------------------------------------------------------------------
>
> Key: SPARK-25220
> URL: https://issues.apache.org/jira/browse/SPARK-25220
> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes
> Affects Versions: 2.4.0
> Reporter: Jonathan A Weaver
> Priority: Trivial
> Labels: Kubernetes
>
> Seperated node selector config option between executors and driver.
> This removes the spark.kubernetes.node.selector config option and seperates
> it to
> spark.kubernetes.driver.selector and spark.kubernetes.executor.selector
> to allow seperate node selectors on drivers and executors.
> My personal use case for this change is that on AWS we have cheap
> spotinstances that can terminate at any moment which is okay for executors
> but not the driver.
> With a single node selector option I am unable to use the spot instances to
> save costs on the executor nodes.
