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 Apache Flink

Flink is an open source framework for distributed stream processing, and has the following features:

  • It provides results that are accurate, even in the case of out-of-order or late-arriving data
  • It is stateful and fault tolerant, and can seamlessly recover from failures while maintaining an exactly-once application state
  • It performs at a large scale, running on thousands of nodes with very good throughput and latency characteristics

The following is a screenshot from the official documentation that shows how Apache Flink can be used:

Another way of viewing the Apache Flink framework is shown in the following screenshot:

All Flink programs are executed lazily, when the program’s main method is executed, the data loading and transformations do not happen directly. Rather, each operation is created and added to the program’s plan. The...
