-------------------------------------------

             Summary: Support --proxy-user for Spark on K8s
                 Key: SPARK-25355
                 URL: https://issues.apache.org/jira/browse/SPARK-25355
             Project: Spark
          Issue Type: New Feature
          Components: Kubernetes
    Affects Versions: 2.4.0
            Reporter: Stavros Kontopoulos


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:
