LTS and it doesnt include overall configuration of hadoop, we have only basic configuration required to start working with hadoop. This tutorial is for configuring Hadoop Single Node Cluster. You may be intrested in Hadoop Multi node Cluster Setup on Linux systems. Step 1 Installing Java. Java is the primary requirement for running hadoop on any system, So make sure you have Java installed on your system using the following command. JavaTM SE Runtime Environment build 1. Java Hot. SpotTM 6. Bit Server VM build 2. If you dont have Java installed on your system, use one of the following links to install it first.
