Patrick Wendell commented on SPARK-2038:
----------------------------------------
Unfortunately after discussion with Reynold, I realized we have to revert this.
The issue is that we can't change parameter names in public API's because scala
allows functions to pass arguments by name:
http://docs.scala-lang.org/tutorials/tour/named-parameters.html
So a change like this could break source compatibility for users.
