Mastering Hadoop 3

By: Chanchal Singh, Manish Kumar

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.

Kerberos authentication


There are various challenges involved in Big Data like storing, processing, and analysis, and managing and securing large data assets. When enterprises started implementing Hadoop, securing Hadoop from an enterprise context became challenging due to the distributed nature of the ecosystem and a wide range of applications that are placed on top of Hadoop. One of the key security considerations in securing Hadoop is authentication.

Kerberos is chosen by the Hadoop team as the component for implementing authentication in Hadoop. Kerberos is a secured network authentication protocol that brings in major authentication for client-server applications without transferring the password through the network. Kerberos implements time-sensitive tickets that are created using symmetric key cryptography, which was chosen over the most widely used SSL-based authentication.

Kerberos advantages

There are different advantages of Kerberos, which are as follows:

  • Better performance: Kerberos...
