Xiangrui Meng 4a171225ba [SPARK-5424][MLLIB] make the new ALS impl take generic ID types ... This PR makes the ALS implementation take generic ID types, e.g., Long and String, and expose it as a developer API. TODO: - [x] make sure that specialization works (validated in profiler) srowen You may like this change:) I hit a Scala compiler bug with specialization. It compiles now but users and items must have the same type. I'm going to check whether specialization really works.
