Github user ilganeli commented on the pull request: https://github.com/apache/spark/pull/3518#issuecomment-70180151 Hi Patrick - thanks for the feedback. I would love to print out the names of the fields but I wasn't able to figure out a way to do that - could you suggest how? I wasn't sure if printing the hash code was useful or not, Josh included it in his original example of a traversal so I figured I'd leave it in. I didn't know if there would be a way to look it up post-facto.
