Apache Spark MOOC study group meetup #1

This will be the first in a series of study sessions here in Bucharest for both EdX MOOCs (Massively Open Online Classes) on Apache Spark.
You can find the EdX MOOCs here:
Intro to big data: https://www.edx.org/course/introduction-big-data-apache-spark-uc-berkeleyx-cs100-1x
Scalable Machine Learning: https://www.edx.org/course/scalable-machine-learning-uc-berkeleyx-cs190-1x

I will bring with me the book "Learning Spark", which has a substantial chapter on Spark's machine learning module called MLlib.
All the interesting code in the book's GitHub repository is here:
