Overview of this book

Apache Hadoop is the most popular platform for big data processing, and can be combined with a host of other big data tools to build powerful analytics solutions. Big Data Analytics with Hadoop 3 shows you how to do just that, by providing insights into the software as well as its benefits with the help of practical examples. Once you have taken a tour of Hadoop 3’s latest features, you will get an overview of HDFS, MapReduce, and YARN, and how they enable faster, more efficient big data processing. You will then move on to learning how to integrate Hadoop with the open source tools, such as Python and R, to analyze and visualize data and perform statistical computing on big data. As you get acquainted with all this, you will explore how to use Hadoop 3 with Apache Spark and Apache Flink for real-time data analytics and stream processing. In addition to this, you will understand how to use Hadoop to build analytics solutions on the cloud and an end-to-end pipeline to perform big data analysis using practical use cases. By the end of this book, you will be well-versed with the analytical capabilities of the Hadoop ecosystem. You will be able to build powerful solutions to perform big data analytics and get insight effortlessly.

Introduction to Hadoop

This chapter introduces the reader to the world of Hadoop and the core components of Hadoop, namely the Hadoop Distributed File System (HDFS) and MapReduce. We will start by introducing the changes and new features in the Hadoop 3 release. Particularly, we will talk about the new features of HDFS and Yet Another Resource Negotiator (YARN), and changes to client applications. Furthermore, we will also install a Hadoop cluster locally and demonstrate the new features such as erasure coding (EC) and the timeline service. As as quick note, Chapter 10, Visualizing Big Data shows you how to create a Hadoop cluster in AWS.

In a nutshell, the following topics will be covered throughout this chapter:

HDFS
- High availability
- Intra-DataNode balancer
- EC
- Port mapping
MapReduce
- Task-level optimization
YARN
- Opportunistic containers
- Timeline service v.2
- Docker containerization
Other changes
Installation of Hadoop 3.1
- HDFS
- YARN
- EC
- Timeline service v.2
