Marcelo Vanzin commented on SPARK-18085:
----------------------------------------
Alright, I have the code in a state that I like (seems stable after some
testing, passes all existing unit tests), so I'll file sub-tasks and start
sending PRs one by one. There's still at least a couple of features I want to
work on, but those can be done in parallel.
