> Hey guys,
> I was wondering, in the file KMeans.scala
> (org/apache/spark/ml/clustering/KMeans.scala), the class KMeansModel is
> private. But only in Scala, not in Java - why is that, and why would that be
> a good idea?
> More concretely, imagine I wanted to extend the KMeans class and still be
> compatible with the API so I can use it in a pipeline. In Scala that's not
> possible, because I can't override the 'fit' method of KMeans, because that
> requires me to return a KMeansModel, which I can't instantiate because the
> constructor of KMeansModel is private.
> If there is no apparent reason we could just make it public, no?
