----------------------------------

             Summary: inconsistent terminology in als api docs and tutorial
                 Key: SPARK-20011
                 URL: https://issues.apache.org/jira/browse/SPARK-20011
             Project: Spark
          Issue Type: Improvement
          Components: MLlib
    Affects Versions: 2.1.0
            Reporter: chris snow
            Priority: Minor


https://spark.apache.org/docs/latest/mllib-collaborative-filtering.html :

bq. rank is the number of latent factors in the model.

https://spark.apache.org/docs/latest/api/scala/index.html#org.apache.spark.mllib.recommendation.ALS$ :

bq. rank - number of features to use

As a noob to ALS, I found this confusing.  Maybe the api docs could state:

bq. rank - number of features to use (also referred to as the number of latent factors)

I'm happy to send in a PR.
