Github user mengxr commented on the pull request: https://github.com/apache/spark/pull/79#issuecomment-36936178 @manishamde Do you mind updating the code style first to make it easy for people who want to review the code? I will mark a few examples. We also need a Spark JIRA ticket for this PR. @etrain It would be great if the optimization you mentioned is documented somewhere in the code or in the guide. It helps understand the code and the comments here will be ignored after this PR gets merged.
