Mastering Apache Storm

By: Ankit Jain

Overview of this book

Apache Storm is a real-time Big Data processing framework that processes large amounts of data reliably, guaranteeing that every message will be processed. Storm allows you to scale your data as it grows, making it an excellent platform to solve your big data problems. This extensive guide will help you understand right from the basics to the advanced topics of Storm. The book begins with a detailed introduction to real-time processing and where Storm fits in to solve these problems. You’ll get an understanding of deploying Storm on clusters by writing a basic Storm Hello World example. Next we’ll introduce you to Trident and you’ll get a clear understanding of how you can develop and deploy a trident topology. We cover topics such as monitoring, Storm Parallelism, scheduler and log processing, in a very easy to understand manner. You will also learn how to integrate Storm with other well-known Big Data technologies such as HBase, Redis, Kafka, and Hadoop to realize the full potential of Storm. With real-world examples and clear explanations, this book will ensure you will have a thorough mastery of Apache Storm. You will be able to use this knowledge to develop efficient, distributed real-time applications to cater to your business needs.

Integration of Storm with Hadoop

The probability that the organizations developing and operating big data applications already have a Hadoop cluster deployed is very high. Also, there is a high possibility that they also have real-time stream processing applications deployed to go along with the batch applications running on Hadoop.

It would be great if we can leverage the already deployed YARN cluster to also run the Storm topologies. This will reduce the operational cost of maintenance by giving you only one cluster to manage instead of two.

Storm-YARN is a project developed by Yahoo! that enables the deployment of Storm topologies over YARN clusters. It enables the deployment of Storm processes on nodes managed by YARN.

The following diagram illustrates how the Storm processes are deployed on YARN:

In the next section, we will see how to set up Storm-YARN.
