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 script for managing HBase processes


When the nodes in the cluster keep growing, you might want to find tools to show and manage the HBase-related processes running in the cluster. As the hadoop user is configured to be able to SSH from the master node to each slave node in the cluster without a password, it is easy for us to write a simple script to achieve this task with SSH login for every node and show/manage the running HBase processes on that node.

As Hadoop/HBase processes run in a Java Virtual Machine (JVM) , our task is to manage these Java processes in the cluster.

In this recipe, we will create a simple script to show all the running Java processes owned by the hadoop user in an HBase cluster.

Getting ready

Start your HBase cluster. Log in to the master node as the user who started the cluster.

We assume that you are running HDFS and HBase as the same user (the hadoop user here).

How to do it...

The instructions to create a simple script to manage HBase processes are as follows...
