Scalastyle and code formatting

[Ryan Skraba <ry...@skraba.com>]

Hello!  Just a quick question about working with the Livy source code
-- I found the existing scalastyle.xml which checks for violations
(although mvn scalastyle:check doesn't seem to work from the root on
master)

Is there a recommended tool for auto-formatting scala code for Livy?
I've been using the default IntelliJ scala formatting limited to lines
that I've changed, but applying the format to an entire file always
generates a lot of noise.

All my best, Ryan
