CompositeInputFormat needs to be ported or an alternative developed
using the 20.2 API. Perhaps a good sub-project?

+1 for attempting this, but beware: DistributedRowMatrix uses map-side
joins, and I'm not sure those are supported in the 0.20+ API. In fact, I
have specifically ran into problems because of this when I tried it in the
past.
Now, some methods can just well, get slower by doing two-pass approaches
(reduce-side join plus a second pass) to one-pass solveable problems, but a
second pass over the data is a pretty bitter pill to swallow. Finding a way
to do a map-side join in 0.20 would be nicer, if possible.

Apologies for missing this; I was actually very interested in doing the
DRM porting to 20.2, considering how much my GSoC project relies on it.
Unless someone has already volunteered...in which case I'd love to help :)

Apologies for the brevity, this was sent from my iPhone

I'd like to see it ported, so RowSimilarityJob can become a method of

Is anybody working on this? Has anybody else looked at it? It seems
to have a few unported dependencies like some of the classifiers.
