Michael Yannakopoulos commented on SPARK-1945:
----------------------------------------------

I am willing to provide a java example for decision trees as well as to enhance 
the java example provided in the naive-bayes section.
What is more, I would like to ask you if there is an equivalent class for 
scala/spark RowMatrix in the equivalent python api.
This is because I would like to provide examples in the dimensionality 
reduction section of mllib documentation using python.

Thanks,
Michael

> Right now some of the Java tabs only say the following:
> "All of MLlib’s methods use Java-friendly types, so you can import and call 
> them there the same way you do in Scala. The only caveat is that the methods 
> take Scala RDD objects, while the Spark Java API uses a separate JavaRDD 
> class. You can convert a Java RDD to a Scala one by calling .rdd() on your 
> JavaRDD object."
> Would be nice to translate the Scala code into Java instead.
> Also, a few pages (most notably the Matrix one) don't have Java examples at 
> all.
