Setting up a ZooKeeper server in standalone mode is straightforward. It is possible to combine multiple components on a single node as well, and for that see further below: Cluster Topology 2. In general, to run a clustered Apache Storm topology, you need a zookeeper node, a nimbus node and N worker nodes. If this guide was useful to you or you have any questions or suggestions, I’d love to heard your comments down below! Cluster Topology 1 I found that using Upstart was much simpler to set up and use though mostly because I used it before and am comfortable with it. The official Storm docs instruct to “Launch daemons under supervision using “storm” script and a supervisor of your choice”, and the most common way of doing that seems to be using supervisord. For restarting failed Zookeeper and Storm components, I wrapped them in Upstart services that respawn automatically when a failure occurs. These instructions should work fine for any hardware running Linux Ubuntu or Debian-based Linux distros, with slight modifications to match particular needs and configurations. In my particular case each host was a Adapteva Parallella running Linaro, a Linux distribution based on Ubuntu for ARM SoC boards. In this How-To article, I show the steps I took to install Apache Storm on a four-node computer cluster consisting of one Zookeeper node, a Nimbus node and two supervisor nodes. Apache StormĪpache Storm is an open-source high-performance, distributed real-time computation framework for processing large streams of data for applications such as realtime analytics, online machine learning, continuous computation, distributed RPC and other big data jobs. We hope you find the below information useful in building your own clusters. To address this need, we have paired Adapteva’s powerful and affordable Parallella boards with Apache Storm to create an ARM-based Ubuntu cluster. The Knowm Development Team needs access to affordable research and development platforms for distributed computing.
