Jongyoul Lee updated SPARK-3223:
--------------------------------
Description: 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. (was: While
