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.

Hadoop security pillars


Before designing security for your Hadoop cluster, you should be very clear about the different aspects of security that have to be incorporated. This section talks about the different pillars of security that are required to make your Hadoop cluster secure and threat-proof. We will discuss each of those pillars in brief in this section. Later, they will be elaborately discussed in different sections of this chapter. 

The following diagram gives you a glimpse of the Hadoop security pillars:

Before discussing the rings in the preceding diagram, we should understand one important aspect of securing the Hadoop cluster, and that is Security Administration. As a Hadoop security administrator, you have to perform the following activities at a high level:

  • Get or develop a means of centralized Hadoop security enablement in terms of automated scripts or security tools.
  • Get or develop a means of a centralized Hadoop monitoring and alerting system. This system should comply with...
