Description

What you would like to be added?

The goal of this issue to use the default spark-operator-spark service account as a fallback when driver.service_account is not specified on the connect API.

Why is this needed?

This is required for simple SDK use cases on the default operator installation when specification of a service account on the API becomes cumbersome.

The fix is a temporary workaround and is meant to be removed once https://github.com/kubeflow/sdk/issues/617 lands.

Love this feature?

Contributor guide

Research direction
Examine the Spark Connect API implementation, specifically the `driver.service account` handling. Identify where the default `spark operator spark` service account is defined (likely in constants.py) and modify the `connect` API to fall back to it when `service account` is not specified. Verify existing tests and update them accordingly.
