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.

Real-time data analysis using Hbase and Mahout


The data, which is readily available using different data streams, needs to be parsed and converted to a meaningful format, which essentially creates value for the business. Hbase integration with Mahout provides the stream that allows us to do clustering in machine learning, which is a way of programmatically orchestrating similar sets of data in a more organized and meaningful way.

Let's say that you have a fruit tasting session where you have different types of fruits, and you want to group people who liked apples, bananas, watermelons, and so on. A small set of data will look staggered, so we have to create some sort of algorithm to do it programmatically. Here is how the data will look before clustering and after clustering. In this section, we can access the underlying data using direct invocation from the Java client.

This can be done in analysis for the purpose of exposing the data in various forms to the data scientist, data analysis...
