Bongani Shongwe commented on SPARK-31800:
-----------------------------------------
I'm also hitting the same issue as OP. I tested using the Spark 3.0 release.
Has there been any other work around or hypothesis on how to overcome the issue?

> {code}
> No changes in settings appear to be able to disable Kerberos. This is when
> running a simple execution of the SparkPi on our lab cluster. The command
> being used is
> {code:java}
> ./bin/spark-submit --master k8s://https://{api_hostname} --deploy-mode
> cluster --name spark-test --class org.apache.spark.examples.SparkPi --conf
> spark.kubernetes.authenticate.driver.serviceAccountName=spark --conf
> spark.kubernetes.namespace=spark-jobs --conf spark.executor.instances=5
> --conf spark.kubernetes.container.image={docker_registry}/spark:spark-3-test
> /opt/spark/examples/jars/spark-examples_2.12-3.0.0-preview2.jar{code}
> It is important to note that this same command, when run on Spark 2.4.5 works
> flawlessly once all of the RBAC accounts are properly setup in Kubernetes.
