Yinan Li commented on SPARK-24434:
----------------------------------
The pod template is basically a pod specification and can contain every
possible pieces of information about a pod. It should look similar to what the
core workload types (deployments and statefulsets for example) use, which
contains a
{{[PodSpec|https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/api/core/v1/types.go#L2636]}}.
> Support user-specified driver and executor pod templates

> Key: SPARK-24434
> URL: https://issues.apache.org/jira/browse/SPARK-24434
> Project: Spark
> Issue Type: New Feature
> Components: Kubernetes
> Affects Versions: 2.4.0
> Reporter: Yinan Li
> Priority: Major
>
> With more requests for customizing the driver and executor pods coming, the
> current approach of adding new Spark configuration options has some serious
> drawbacks: 1) it means more Kubernetes specific configuration options to
> maintain, and 2) it widens the gap between the declarative model used by
> Kubernetes and the configuration model used by Spark. We should start
> designing a solution that allows users to specify pod templates as central
> places for all customization needs for the driver and executor pods.
