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

             Summary: Add StopWordsRemover as a transformer
                 Key: SPARK-8169
                 URL: https://issues.apache.org/jira/browse/SPARK-8169
             Project: Spark
          Issue Type: New Feature
          Components: ML
    Affects Versions: 1.5.0
            Reporter: Xiangrui Meng


StopWordsRemover takes a string array column and outputs a string array column with all defined stop words removed. The transformer should also come with a standard set of stop words as default.

{code}
val stopWords = new StopWordsRemover()
  .setInputCol("words")
  .setOutputCol("cleanWords")
  .setStopWords(Array(...)) // optional
val output = stopWords.transform(df)
{code}
