Github user manishamde commented on the pull request: https://github.com/apache/spark/pull/79#issuecomment-37213685 Thanks for another round of reviews @mengxr. I will fix these style issues, answer your comments and add more documentation around the optimizations later today. In general, I wonder whether we could add these checks to scalastyle to be cognizant of the style rules during development. May be we could also update the scala code style guide to reflect these requirements. For somebody, who likes consistency but codes in multiple languages/codebases in a day, it's good to have these forced guidelines for easier development. Also, it reduces the style-checking during the review which would reduce the burden on the reviewers as well. Thanks again for the detailed reviews.
