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

Simple scripts to report the status of the cluster


Besides the health of the HBase-related daemons and their logs, what you might want to monitor is the overview of the current status of the cluster. This status basically includes:

  • The HBase hbck result showing whether the HBase tables are consistent

  • The Hadoop fsck result showing whether HDFS is healthy

  • The remaining HDFS space

In this recipe, we will create a check_hbase Nagios plugin to perform the task of monitoring. We will install our check_hbase plugin on the master node of the cluster, and remotely execute it with Nagios from the monitor server using the NRPE Nagios plugin.

Getting ready

We assume that you have installed and configured the Nagios NRPE plugin on your monitor and master server. If you have not installed it yet, refer to the previous recipe for detailed installation instructions.

How to do it...

The following are instructions to get the status of the HBase cluster and monitor it by Nagios:

  1. 1. Create a check_hbase script...
