Mainframe is brought before the Commander."So, this is the Joe nerd. What do they call you, Dataframe, Mainframe? No matter. Here, you are nothing but scum. Tell me, what precious information is on your harddrive".Mainframe stands there, stoicly. His icy glare is fixed on the reflective plate that covers the enemy leader's face."Your silence will serve you nothing, here. However, some useful information will give you a quick and relatively painless death. Nothing? Very well. Troopers, take this scum to Night Adder. See to it he is given a very thorough questioning. Then, return him to me".

In this fast-paced coding tour I’ll show you Spark's ability to rapidly process Big Data. I'll demonstrate extracting information with RDDs, querying data using DataFrames, visualizing and plotting data, and show you how to create a machine-learning pipeline with Spark-ML and MLLib. We'll also discuss the internals which make Spark 10-100 times faster than Hadoop MapReduce and Hive.
