[SPARK-6252] [mllib] Added getLambda to Scala NaiveBayes Note: not relevant for Python API since it only has a static train method Author: Joseph K. Bradley <joseph.kurata.brad...@gmail.com> Author: Joseph K. Bradley <jos...@databricks.com> Closes #4969 from jkbradley/SPARK-6252 and squashes the following commits: a471d90 [Joseph K.
