Overview of this book

Apache Hadoop is one of the most popular big data solutions for distributed storage and for processing large chunks of data. With Hadoop 3, Apache promises to provide a high-performance, more fault-tolerant, and highly efficient big data processing platform, with a focus on improved scalability and increased efficiency. With this guide, you’ll understand advanced concepts of the Hadoop ecosystem tool. You’ll learn how Hadoop works internally, study advanced concepts of different ecosystem tools, discover solutions to real-world use cases, and understand how to secure your cluster. It will then walk you through HDFS, YARN, MapReduce, and Hadoop 3 concepts. You’ll be able to address common challenges like using Kafka efficiently, designing low latency, reliable message delivery Kafka systems, and handling high data volumes. As you advance, you’ll discover how to address major challenges when building an enterprise-grade messaging system, and how to use different stream processing systems along with Kafka to fulfil your enterprise goals. By the end of this book, you’ll have a complete understanding of how components in the Hadoop ecosystem are effectively integrated to implement a fast and reliable data pipeline, and you’ll be equipped to tackle a range of real-world problems in data pipelines.

Securing Hadoop networks


There are multiple steps in securing Hadoop networks. The first step in designing the Hadoop cluster is to set up the network. In the next subsections, we will talk about different types of networks, network firewall usage and different tools available in the market to secure the network.

Segregating different types of networks

Segregating or segmenting your enterprise network is one of the most basic aspects of securing your Hadoop network. In general, segmentation is one of the practices followed by enterprises. However, when you are setting up a Hadoop cluster you need to ensure that certain aspects are in your network design.

You should think about the following aspects one by one:

  • What kind of traffic would there be? Are we getting any traffic from the internet or will it all be internal network traffic?
  • Do we have inbound or outbound traffic over internet or intranet? What services would have inbound or outbound traffic, or both?
  • Does your Hadoop cluster have integrations...
