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.

Monitoring Hbase with Ganglia


The Ganglia open source project is a scalable distributed system designed to monitor clusters and grids while minimizing the impact on their performance. When you enable Ganglia on your cluster, you can generate reports and view the performance of the cluster as a whole, as well as inspect the performance of individual node instances.

For more information about the Ganglia open source project, go to http://ganglia.info/. For more information about using Ganglia with Amazon EMR clusters, see the Monitor Performance with Ganglia recipe.

You configure Ganglia for HBase using the configure-hbase-for-ganglia bootstrap action. This bootstrap action configures HBase to publish metrics to Ganglia.

Note

You must configure HBase and Ganglia when you launch the cluster; Ganglia reporting cannot be added to a running cluster. Once the cluster is launched with Ganglia reporting configured, you can access Ganglia graphs and reports using the graphical interface running on the...
