Subject [jira] [Created] (SPARK-20485) Split ALS.scala into multiple files
Date Thu, 27 Apr 2017 01:55:04 GMT
Daniel Li created SPARK-20485:
---------------------------------

             Summary: Split ALS.scala into multiple files
                 Key: SPARK-20485
                 URL: https://issues.apache.org/jira/browse/SPARK-20485
             Project: Spark
          Issue Type: Improvement
          Components: ML, MLlib
    Affects Versions: 2.1.0
            Reporter: Daniel Li
            Priority: Trivial


The file {{/mllib/src/main/scala/org/apache/spark/ml/recommendation/ALS.scala}} currently
contains four top-level classes that span 1,500+ lines.  To make the file easier to navigate,
and to bring it in line with the [Scala style guide|http://docs.scala-lang.org/style/files.html],
I propose we split it into four files holding their respective classes: {{ALS.scala}}, {{ALSParams.scala}},
{{ALSModel.scala}}, and {{ALSModelParams.scala}}.
