> SPARK-23257 adds kerberized hdfs support for Spark on K8s. A major addition needed is
the support for proxy user. A proxy user is impersonated by a superuser who executes operations
on behalf of the proxy user. More on this:

> [https://github.com/spark-notebook/spark-notebook/blob/master/docs/proxyuser_impersonation.md]
> This has been implemented for Yarn upstream and Spark on Mesos here:
> [https://github.com/mesosphere/spark/pull/26]
> [~ifilonenko] creating this issue according to our discussion.
