Looks like you're not registering the input param correctly.
Below are examples from the Spark Java source that show how to build a
custom transformer. Note that a Model is a Transformer.
Also, that chimpler/wordpress/naive bayes example is a bit dated. I tried
to implement it a while ago, but
I am trying to write a trivial transformer I use use in my pipeline. I am
using java and spark 1.5.2. It was suggested that I use the Tokenize.scala
class as an example. This should be very easy how ever I do not understand
Scala, I am having trouble debugging the following exception.
Any help
