RDD based Machine Learning API

As time goes by, Spark community decided to move RDD based machine learning API to maintenance mode in Spark 2.0, and presumably remove it completly in version 3.0 later in the future. Lifetime of the following examples is limited then.

• Using classification to build model for predicting customer behavior
• Naive Bayes exploiting TF-IDF for Spam classification
• Using regression for predicting House prices
• Images classification with Convolutional Neural Networks, Deeplearning4j and Spark
