About this book Introduction Big Data Analytics with Spark is a step-by-step guide for learning Spark, which is an open-source fast and general-purpose cluster computing framework for large-scale data analysis. You will learn how to use Spark for different types of big data analytics projects, including batch, interactive, graph, and stream data analysis as well as machine learning. In addition, this book will help you become a much sought-after Spark expert. Spark is one of the hottest Big Data technologies. The amount of data generated today by devices, applications and users is exploding.

But the exciting thing for me about it has always been what it opens up for complex analytics. With a paradigm that supports iterative algorithms and interactive exploration, Spark is finally an open source framework that allows a data scientist to be productive with large data sets.

I think the best way to teach data science is by example. To that end, my colleagues and I have put together a book of applications, trying to touch on the interactions between the most common algorithms, data sets, and design patterns in large-scale analytics.

After that, each chapter will comprise a self-contained analysis using Spark. The second chapter will introduce the basics of data processing in Spark and Scala through a use case in data cleansing. The remaining chapters are a bit more of a grab bag and apply Spark in slightly more exotic applications—for example, querying Wikipedia through latent semantic relationships in the text or analyzing genomics data.

Using Code Examples Supplemental material code examples, exercises, etc.

This book is here to help you get your job done. In general, if example code is offered with this book, you may use it in your programs and documentation.

For example, writing a program that uses several chunks of code from this book does not require permission. Answering a question by citing this book and quoting example code does not require permission.

Big data analytics on Apache Spark

When people say that we live in an age of big data they mean that we have tools for collecting, storing, and processing information at a scale previously unheard of.

Distributed systems like Apache Hadoop have found their way into the mainstream and have seen widespread deployment at organizations in nearly every field. But just as a chisel and a block of stone do not make a statue, there is a gap between having access to these tools and all this data and doing something useful with it.

This is where data science comes in. Just as sculpture is the practice of turning tools and raw material into something relevant to nonsculptors, data science is the practice of turning tools and raw data into something that non—data scientists might care about.

These are the kinds of analyses we are going to talk about in this book. For a long time, open source frameworks like R, the PyData stack, and Octave have made rapid analysis and model building viable over small data sets. With fewer than 10 lines of code, we can throw together a machine learning model on half a data set and use it to predict labels on the other half.

With a little more effort, we can impute missing data, experiment with a few models to find the best one, or use the results of a model as inputs to fit another. What should an equivalent process look like that can leverage clusters of computers to achieve the same outcomes on huge data sets? The right approach might be to simply extend these frameworks to run on multiple machines to retain their programming models and rewrite their guts to play well in distributed settings.
