-------------------------------------
Hi [~vanzin]
There is an opened Jira SPARK-28042 for this.
> Support mapping spark.local.dir to hostPath volume
> --------------------------------------------------
>
> Key: SPARK-27499
> URL: https://issues.apache.org/jira/browse/SPARK-27499
> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes
> Affects Versions: 3.0.0
> Reporter: Junjie Chen
> Priority: Minor
>
> Currently, the k8s executor builder mount spark.local.dir as emptyDir or
> memory, it should satisfy some small workload, while in some heavily workload
> like TPCDS, both of them can have some problem, such as pods are evicted due
> to disk pressure when using emptyDir, and OOM when using tmpfs.
> In particular on cloud environment, users may allocate cluster with minimum
> configuration and add cloud storage when running workload. In this case, we
> can specify multiple elastic storage as spark.local.dir to accelerate the
> spilling.
