Besides API stability concerns, models constructed directly from users
rather than returned by ALS may not work well. The userFeatures and
productFeatures are both with partitioners so we can perform quick
lookup for prediction. If you save userFeatures and productFeatures
and load them back, it is very likely the partitioning info is
missing. That being said, we will try to address model export/import
in v1.3: https://issues.apache.org/jira/browse/SPARK-4587 . -Xiangrui
