[jira] [Commented] (SPARK-12836) spark enable both driver run
executor & write to HDFS
[ https://issues.apache.org/jira/browse/SPARK-12836?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15197120#comment-15197120 ]
Lior Chaga commented on SPARK-12836:
------------------------------------
I used the --no-switch_user mesos config, and it worked. Writing to hadoop was with HADOOP_USER_NAME, while spark executors were running with the mesos-slave user permissions.
