Big Data Analytics with Java


Overview of this book

This book covers case studies such as sentiment analysis on a tweet dataset, recommendations on a movielens dataset, customer segmentation on an ecommerce dataset, and graph analysis on actual flights dataset. This book is an end-to-end guide to implement analytics on big data with Java. Java is the de facto language for major big data environments, including Hadoop. This book will teach you how to perform analytics on big data with production-friendly Java. This book basically divided into two sections. The first part is an introduction that will help the readers get acquainted with big data environments, whereas the second part will contain a hardcore discussion on all the concepts in analytics on big data. It will take you from data analysis and data visualization to the core concepts and advantages of machine learning, real-life usage of regression and classification using Naïve Bayes, a deep discussion on the concepts of clustering,and a review of simple neural networks on big data using deepLearning4j or plain Java Spark code. This book is a must-have book for Java developers who want to start learning big data analytics and want to use it in the real world.

In this chapter, we learned about graph analytics. We saw how graphs can be built even on top of massive big datasets. We learned how Apache Spark can be used to build these massive graphs and in the process we learned about the new library GraphFrames that helps us in building these graphs. We started with the basics of graphs as to how graphs can be built and represented and later we explored the different forms of analytics that can be run on those graphs be it path-based analytics involving algorithms such as breadth first search or connectivity analytics involving the degrees of connection. A flight dataset was used to explore the different forms of graph analytics while using a real-world dataset.

Up until now, we have mostly used the data and the program in a batch mode. In the next chapter, we will see how big data can even be used in our analysis at real time.
