> `ExecutorKubernetesCredentialsFeatureStep` applies `spark.kubernetes.authenticate.executor.serviceAccountName`, falling back to the value of `spark.kubernetes.authenticate.driver.serviceAccountName`, only when the executor pod template names no service account. When the template does name one, the configured account is discarded and nothing is written to the log -- the step does not even mix in `Logging`.
> SPARK-58872 added a WARN for the analogous situation on the driver side, where submitted driver credentials take precedence over `spark.kubernetes.authenticate.driver.serviceAccountName`, and documented it in `running-on-kubernetes.md`. The two are not the same code path, but the user sees the same thing: a service account configuration that is set, does not apply, and says nothing about why.
> Follow-up to SPARK-58910, which fixed the guard that decides whether the template names an account. That fix is a bug fix headed for the maintenance branches, so adding the warning there would carry an improvement onto branches it does not belong on.
