> 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.
