HBase Administration Cookbook

Overview of this book

As an Open Source distributed big data store, HBase scales to billions of rows, with millions of columns and sits on top of the clusters of commodity machines. If you are looking for a way to store and access a huge amount of data in real-time, then look no further than HBase.HBase Administration Cookbook provides practical examples and simple step-by-step instructions for you to administrate HBase with ease. The recipes cover a wide range of processes for managing a fully distributed, highly available HBase cluster on the cloud. Working with such a huge amount of data means that an organized and manageable process is key and this book will help you to achieve that.The recipes in this practical cookbook start from setting up a fully distributed HBase cluster and moving data into it. You will learn how to use all of the tools for day-to-day administration tasks as well as for efficiently managing and monitoring the cluster to achieve the best performance possible. Understanding the relationship between Hadoop and HBase will allow you to get the best out of HBase so the book will show you how to set up Hadoop clusters, configure Hadoop to cooperate with HBase, and tune its performance.

Preface

Setting up Nagios to monitor HBase processes


Monitoring HBase-related processes in the cluster is an important part of operating HBase. A basic monitoring is done by running health checks on the HBase processes and notifying the administrators if any process is down.

Nagios is a popular, open source monitoring software used to watch hosts, services, and resources, and alert users when something goes wrong and when it gets recovered again. Nagios can be easily extended by custom-modules, which are called plugins. The check_tcp plugin is shipped with the Nagios installation. We can use this plugin to send a ping to a Hadoop/HBase daemon's RPC port, to check whether the daemon is alive.

In this recipe, we will set up a monitor server running Nagios to watch all the HBase-related processes in the entire cluster. We will configure Nagios to send us e-mail notifications if any Hadoop/HBase/ZooKeeper process is down.

Getting ready

You will need a monitor server to run Nagios on. We assume that...
