Apache Spark 2.x for Java Developers

By: Sourav Gulati, Sumit Kumar

Overview of this book

Apache Spark is the buzzword in the big data industry right now, especially with the increasing need for real-time streaming and data processing. While Spark is built on Scala, the Spark Java API exposes all the Spark features available in the Scala version for Java developers. This book will show you how you can implement various functionalities of the Apache Spark framework in Java, without stepping out of your comfort zone. The book starts with an introduction to the Apache Spark 2.x ecosystem, followed by explaining how to install and configure Spark, and refreshes the Java concepts that will be useful to you when consuming Apache Spark's APIs. You will explore RDD and its associated common Action and Transformation Java APIs, set up a production-like clustered environment, and work with Spark SQL. Moving on, you will perform near-real-time processing with Spark streaming, Machine Learning analytics with Spark MLlib, and graph processing with GraphX, all using various Java packages. By the end of the book, you will have a solid foundation in implementing components in the Spark framework in Java to build fast, real-time applications.

In this chapter, we discussed the Spark Graphx library. We started with graph abstraction provided in the Graphx library known as the Property Graph and then we discussed various graph operations provided by the Graphx library with code examples. Finally, we discussed built-in graph algorithms provided by the Graphx library along with code examples.

The motive of this book is to explain concepts of Spark in detail and provide their implementations in Java and this is what we have focused while writing each chapter of this book. We would like to thank all the readers of this book and hope that this book has served the purpose of learning that you aspired for. Your feedback is precious for us so please feel free to provide your feedback, at Packt Publishing for this book. As said, once you know how to walk you can always make efforts to run, we hope that this book will help readers to walk on the road of Apache Spark and guide them to achieve their goals.
