Email Spam Classifier Java Application with SPARK

In this post we are going to develop an application for the purpose of detecting spam emails.The algorithm which will be used is Logistic Regression, implementation from SPARK MLib. No deep knowledge on the field is required as the topics are described from a high level perspective as possible. Full working code is provided together with a running application for further experiments on your choice of emails(please last section). Logistic Regression is an algorithm used for classification problems. In Classification problems we are given a lot of labeled data(example spam and not spam) and when a new example is coming we want to know which category it belongs to.
