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

             Summary: runAsSparkUser cannot change HDFS write permission properly in mesos cluster mode
                 Key: SPARK-3223
                 URL: https://issues.apache.org/jira/browse/SPARK-3223
             Project: Spark
          Issue Type: Bug
          Components: Input/Output, Mesos
    Affects Versions: 1.0.2
            Reporter: Jongyoul Lee
            Priority: Blocker
             Fix For: 1.1.0


While running mesos with --no-switch_user option, HDFS account name is different from driver and executor. It makes a permission error at last stage. Executor's id is mesos' user id and driver's id is who runs spark-submit. So, moving output from _temporary/path/to/output/part-xxxx to /output/path/part-xxxx fails because of permission error. The solution for this is only setting SPARK_USER to HADOOP_USER_NAME when MesosExecutorBackend calls runAsSparkUser.
