Github user rawkintrevo commented on the pull request: https://github.com/apache/flink/pull/1397#issuecomment-170162685 on your second point- I agree that Enum would be better for human readable variable setting, but if one was doing a grid parameter search it would be easier to search over a range of integers than having to establish an array of specifically named variables. Not significantly harder, but still slightly more tedious. Further, since I'm just learning scala- limited research/understanding leads me to believe 1) scala doesn't have an enum that works just like Java, and 2) changing the cases to more informative string names would achieve the desired goal? In the mean time working on documentation and reverting the indentation (which I thought I had already done), and thanks for bearing with me as I am still learning.
