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.

Share ZooKeeper between Storm and Kafka

We can share the same ZooKeeper ensemble between Kafka and Storm as both store the metadata inside the different znodes (ZooKeeper coordinates between the distributed processes using the shared hierarchical namespace, which is organized similarly to a standard file system. In ZooKeeper, the namespace consisting of data registers is called znodes).

We need to open the ZooKeeper client console to view the znodes (shared namespace) created for Kafka and Storm.

Go to ZK_HOME and execute the following command to open the ZooKeeper console:

> bin/

Execute the following command to view the list of znodes:

> [zk: localhost:2181(CONNECTED) 0] ls /[storm, consumers, isr_change_notification, zookeeper, admin, brokers]

Here, consumers, isr_change_notification, and brokers are the znodes and the Kafka is managing its metadata information into ZooKeeper at this location.

Storm manages its metadata inside the Storm znodes in ZooKeeper.
