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
