@tgravescs `spark.driver.extrClassPath` and `spark.executor.extraClassPath`
exist mostly to provide equivalent support to setting SPARK_CLASSPATH which has
always been around in previous versions. I also don't like the fact that we
support this kind of thing... we could make it unsupported on YARN if you
want, or undocumented.
I tested this on a local YARN cluster. We're doing some QA this week on
YARN 2.2 clusters as well.
