Github user mengxr commented on the pull request: https://github.com/apache/spark/pull/1379#issuecomment-49682997 It is easier to review if it passes the tests. @SparkQA shows new public classes and interface changes. Could you remove the data file and generate some synthetic data for unit tests? Thanks!
