@sryza - I don't think this is relevant to the YARN codepath. AFAIK YARN
doesn't use the ./spark-class script to launch the YARN application master
(which embeds the driver program). I'm not totally sure how that JVM is
actually launched though... couldn't figure it out on a quick glance at that
code.
