Github user manishamde commented on the pull request: https://github.com/apache/spark/pull/79#issuecomment-37262156 @mengxr Thanks for such a detailed review. The code is already in a much better shape after incorporating your suggested changes. I have fixed the straightforward code style issues and will commit shortly. I still need to make more code style changes and document the findBestSplit method in detail. I need some more time to think about your implementation suggestions. I also need to seriously consider @srowen's suggestion about adding multi-class classification in this version of the PR. I will get back to you on this tomorrow.
