Sean Owen resolved SPARK-9515.
------------------------------
Resolution: Invalid
Yes I think one of the problem is that you aren't using spark-submit. You
haven't shown code or said more about why you're not using spark-submit. This
is not a valid JIRA; it doesn't completely describe a problem or solution.
