Brian O'Keefe commented on SPARK-6532:
--------------------------------------
Thanks. I did not understand that scalastyle was not part of the compiler
(Scala novice as I said). I will try to dig in deeper, though honestly my
first priority will probably be trying to figure out how to bypass the
scalastyle part of the build process now that I understand what it does :)
