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

             Summary: Strength consistency for supporting string params: case-insensitive or not
                 Key: SPARK-22331
                 URL: https://issues.apache.org/jira/browse/SPARK-22331
             Project: Spark
          Issue Type: Improvement
          Components: MLlib
    Affects Versions: 2.2.0
            Reporter: yuhao yang
            Priority: Minor


Some String params in ML are still case-sensitive, as they are checked by ParamValidators.inArray.

For consistency in user experience, there should be some general guideline in whether String params in Spark MLlib are case-insensitive or not. 

I'm leaning towards making all String params case-insensitive where possible.
