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

HBase Master web UI


The HBase Master web UI is a simple but useful tool, to get an overview of the current status of the cluster. From its page, you can get the version of the running HBase, its basic configuration, including the root HDFS path and ZooKeeper quorum, load average of the cluster, and a table, region, and region server list.

Furthermore, you can manually split a region using a particular boundary row key. This is useful when you turn off the automatic region splitting of your cluster.

Getting ready

Make sure the port for your master page, which has a default value of 60010, is opened to your client computer from your network firewall. If you are running your cluster on Amazon EC2, you can open the port from AWS Management Console | Amazon EC2 | NETWORK & SECURITY | Security Groups | Inbound.

How to do it...

Access the following URL from your web browser:

http://hbase_master_server:60010/master.jsp

Note

You need to change hbase_master_server to the hostname of your HBase master...
