> 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. HADOOP_USER_NAME is used when FileSystem get user.
