             Summary: Multiple --py-files command line options to spark-submit replace instead of adding to previous options
                 Key: SPARK-4566
                 URL: https://issues.apache.org/jira/browse/SPARK-4566
             Project: Spark
          Issue Type: Bug
            Reporter: Phil Roth
            Priority: Minor


If multiple --py-files are specified to spark-submit, previous lists of files are replaced instead of added to. This is certainly a minor issue, but it cost me a lot of debugging time.

If people want the current behavior to stay the same, I would suggest updating the help messages to highlight that the suggested usage is one option with a comma separated list of files.

If people want this behavior updated, I'd love to submit a pull request in the next day or two. I think it would be a perfect small task to get me started as a contributor.
