> We have a few situations when algorithm-facing API has Spark dependencies creeping in.

> In particular, we know of the following cases:
> -(1) checkpoint() accepts Spark constant StorageLevel directly;-
> -(2) certain things in CheckpointedDRM;-
> -(3) drmParallelize etc. routines in the "drm" and "sparkbindings" package.-
> -(5) drmBroadcast returns a Spark-specific Broadcast object-
> (6) Stratosphere/Flink conceptual api changes.
> *Current tracker:* PR #1 https://github.com/apache/mahout/pull/1 - closed, need new PR
for remaining things once ready.
> *Pull requests are welcome*.
