--------------------------------------
I'm exploring this.
> Add support for ESS in Spark sidecar
> ------------------------------------
>
> Key: SPARK-32642
> URL: https://issues.apache.org/jira/browse/SPARK-32642
> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes
> Affects Versions: 3.1.0
> Reporter: Holden Karau
> Assignee: Holden Karau
> Priority: Major
>
> For Spark on Kubernetes there are multiple ways to achieve dynamic scaling.
> Unlike in YARN mode ESS on Spark on K8s as a sidecar would not help with
> dynamic scaling. Instead this helps with the situations where the executor
> JVM may be overloaded or crash. If we do this as a sidecar we can share the
> same mounts between the executor and the external shuffle storage.
