Hi Nick. I would write something up, however, to be quite honest I don't yet
truly understand the cause of the issue. Additionally, I've got ways to go
before I understand Spark's class loading model. Nor have I yet tested this in
a clustered environment. In other words, not quite ready to produce a piece of
doc that's really accurate.
