Practical Big Data Analytics

By: Nataraj Dasgupta

Overview of this book

Big Data analytics relates to the strategies used by organizations to collect, organize, and analyze large amounts of data to uncover valuable business insights that cannot be analyzed through traditional systems. Crafting an enterprise-scale cost-efficient Big Data and machine learning solution to uncover insights and value from your organization’s data is a challenge. Today, with hundreds of new Big Data systems, machine learning packages, and BI tools, selecting the right combination of technologies is an even greater challenge. This book will help you do that. With the help of this guide, you will be able to bridge the gap between the theoretical world of technology and the practical reality of building corporate Big Data and data science platforms. You will get hands-on exposure to Hadoop and Spark, build machine learning dashboards using R and R Shiny, create web-based apps using NoSQL databases such as MongoDB, and even learn how to write R code for neural networks. By the end of the book, you will have a very clear and concrete understanding of what Big Data analytics means, how it drives revenues for organizations, and how you can develop your own Big Data analytics solution using the different tools and methods articulated in this book.

Preface

Hands-on with CDH


In this section, we will utilize the CDH QuickStart VM to work through some of the topics that have been discussed in the current chapter. The exercises do not have to be necessarily performed in a chronological order and are not dependent upon the completion of any of the other exercises.

We will complete the following exercises in this section:

  • WordCount using Hadoop MapReduce
  • Working with the HDFS
  • Downloading and querying data with Apache Hive

WordCount using Hadoop MapReduce

In this exercise, we will be attempting to count the number of occurrences of each word in one of the longest novels ever written. For the exercise, we have selected the book Artamène ou le Grand Cyrus written by Georges and/or Madeleine de Scudéry between 1649-1653. The book is considered to be the second longest novel ever written, per the related list on Wikipedia (https://en.wikipedia.org/wiki/List_of_longest_novels). The novel consists of 13,905 pages across 10 volumes and has close to two million...
