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.

Storm/Heron


Apache Storm is a distributed real-time computing system that processes a large volume of high velocity data. Unlike Spark, it does not create micro batches instead, it gives us the ability to process events in real-time mode. Applications where even a delay of seconds can cause a big loss could not go with a near real-time processing engine like Spark. There are a large number of companies that are using Apache Storm for processing events in real time for use cases such as fraud detection, recommendation engines, identifying suspicious activity, and so on. 

Note

Apache Storm is a distributed real-time processing engine that provides the ability to process events as quick as they arrive to the node. It is super fast and can process millions of events per machine. Storm is reliable in processing both bounded and unbounded streams of event. 

Deep dive into the Storm/Heron architecture

Like other distributed processing engines, Apache Storm is also built using the master-slave architecture...
