> Transformer mentioned first in [SPARK-5571] based on suggestion from [~aloknsingh].  Very standard NLP preprocessing task.

> We have one scala stemmer in scalanlp%chalk https://github.com/scalanlp/chalk/tree/master/src/main/scala/chalk/text/analyze  which can easily copied (as it is apache project) and is in scala too.
> I think this will be better alternative than lucene englishAnalyzer or opennlp.
> Note: we already use the scalanlp%breeze via the maven dependency so I think adding scalanlp%chalk dependency is also the options. But as you had said we can copy the code as it is small.
