Hi Yasemin, If you can convert your user IDs to Integers in pre-processing (if you have < a couple billion users), that would work. Otherwise... In Spark 1.3: You may need to modify ALS to use Long instead of Int. In Spark 1.4: spark.ml.recommendation.ALS (in the Pipeline API) exposes ALS.train as a DeveloperApi to allow users to use Long instead of Int. We're also thinking about better ways to permit Long IDs.
