I think this was somewhat intentionally designed to only take a single
required argument. Checkout the existing docs for the history server:
http://spark.apache.org/docs/latest/monitoring.html
Doesn't this also break compatibility with 1.0 as well?
Separately, I'd rather not overload `-D` in general. This seems to actually
have different syntax than the normal `-D` where you do `-Dkey=value`. Here
it's `-D key value`.
