In this easy to follow tutorial, learn the basics of Spark DataFrames, how they're composed of RDDs and what they allow you to do in Scala. They're a similar abstraction to pandas DataFrames or R's DataFrames.
In this short article, we'll go over what Broadcast variables are, some of their uses, and how you should try and leverage them in your projects. We'll be covering topics like the broadcast join to keep your cluster from having to do too much work!
In this tutorial we're gong to set up a complete predictive modeling pipeline in Spark using DataFrames, Pipelines and MLlib. The first part of this tutorial will explain some of the basic concepts that we're going to need to build this model, walk you through how to download the data we'll use, and lastly create our Spark Cluster on Amazon AWS and read and write from AWS S3!
