Gabor Somogyi commented on SPARK-25355:
---------------------------------------
I've had a deeper look and HADOOP_TOKEN_FILE_LOCATION is a generic issue
together w/ --proxy-user. Fixing only the K8S side is good direction but not
enough from my perspective.

> 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://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/Superusers.html]
> [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.
