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.

Viewing the Hbase user interface


To view the Hbase UI master, some configuration needs to be done so that the access is via proxy, and if fully secure to your cluster only.

How to do it …

There are two ways to connect to the cluster, as follows:

Using SSH and via Browser:

As we are more browser-centric here, we will be connecting using Firefox and Chrome.

  1. On Mac OS X, choose Applications>Utilities>Terminal and open a Terminal:

    Replace hbase03.pem , replace 8157 with an unused , local port number, and replace ec2-54-252-202-32.ap-southeast-2.compute.amazonaws.com with the master public DNS name of your cluster.

  2. Now you can use the following command:

    ssh –i ~/hbase03.pem –N –D 8157 hadoop@ ec2-54-252-202-32.ap-southeast-2.compute.amazonaws.com
    

    Note

    D is used for dynamic port forwarding, which allows you to specify a local port used to forward data to all remote ports on the master node's local webserver. Dynamic port forwarding also creates a local SOCKS proxy listening on the specified in the...
