HBase High Performance Cookbook

By: Ruchir Choudhry

Overview of this book

Apache HBase is a non-relational NoSQL database management system that runs on top of HDFS. It is an open source, disturbed, versioned, column-oriented store and is written in Java to provide random real-time access to big Data. We’ll start off by ensuring you have a solid understanding the basics of HBase, followed by giving you a thorough explanation of architecting a HBase cluster as per our project specifications. Next, we will explore the scalable structure of tables and we will be able to communicate with the HBase client. After this, we’ll show you the intricacies of MapReduce and the art of performance tuning with HBase. Following this, we’ll explain the concepts pertaining to scaling with HBase. Finally, you will get an understanding of how to integrate HBase with other tools such as ElasticSearch. By the end of this book, you will have learned enough to exploit HBase for boost system performance.

Terminating an HBase cluster


Before terminating the cluster, it is advisable to make sure that a backup of the data is done, and the nodes are not writing to the master so that there is consistence in the data.

How to do it…

The termination step is very simple—simply go the cluster list, select the cluster, and click on the Terminate button. This will start the logical termination and eventually the resources will be released to other applications running is the same cluster (at the hardware level):
