----------------------------------
[~dongjoon] this ticket is duplicated with SPARK-43342
> driver and executors shared same Kubernetes PVC in Spark 3.4+

> Key: SPARK-43329
> URL: https://issues.apache.org/jira/browse/SPARK-43329
> Project: Spark
> Issue Type: Bug
> Components: Kubernetes
> Affects Versions: 3.4.0
> Reporter: comet
> Priority: Major
>
> I able to shared same PVC for spark 3.3. but on Spark 3.4 onward. i get below
> error. I would like all the executors and driver to mount the same PVC. Is
> this a bug ? I don't want to use SPARK_EXECUTOR_ID or OnDemand because
> otherwise each of the executors will use an unique and separate PVC.
>
> Error message is "should contain OnDemand or SPARK_EXECUTOR_ID when requiring
> multiple executors"
>
> below is how I enabled it pvc in spark 3.3 and it works, but does not work in
> Spark 3.4
> {code:sh}
> spark.kubernetes.driver.volumes.persistentVolumeClaim.rwxpvc.options.claimName=rwxpvc
>
> --conf
> spark.kubernetes.driver.volumes.persistentVolumeClaim.rwxpvc.mount.path=/opt/spark/work-dir
>
> --conf
