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.

Connecting to an Hbase cluster using the command line


How to do it…

  1. You can alternatively SSH to the node and see the details as follows:

  2. Once you have connected to the cluster, you can perform all the tasks which you can perform on local clusters.

    The preceding screenshot gives the details of the components we selected while installing the cluster.

  3. Let's connect to the Hbase shell to make sure all the components are connecting internally and we are able to create a sample table.

How it works…

The communication between your machine and the Hbase cluster works by passing a key every time a command is executed; this allows the communication to be private.

The shell becomes the remote shell that connects to the Hbase master via a private connection. All the base shell commands such as put, create, and scan get all the known Hbase commands.
