I think a better description is that this project is about ML algorithms that need large scale.
If you have very inexpensive feature selection that can run sequentially, then it probably doesn't matter to use hadoop/mahout for that. Some forms of feature extraction is very expensive, however, and could definitely benefit from parallelism. For instance, you could imagine that the feature extraction step involves a large scale non-deterministic clustering. It might even be that the the feature extraction requires parallel processing, but the actual learning algorithm does not.
