Subject ONI-LDA-C

Hi all,
Vartika mentioned this in a hallway conversation, we decided to bring it up
here.

ONI's LDA implementation
<https://github.com/Open-Network-Insight/oni-lda-c/blob/01f1d6fa81ba0b3aa1080ca3a3ebd5c679720735/license.txt>
is
written in C, but most importantly, is GPL Licensed. And, from the looks of
it, it's a hard dependency.

So, as we migrate to Apache, this needs to be changed. Either:
A. it needs to be a softer dependency, or
B. we need to find a substitute.

I have noticed Spark MLLib has LDA, and given that this algorithm is being
called from Spark anyways, Option B (with Spark) would be a reasonable
choice.

What do others think? Any other options?

Mark
