Single-node installation

Let's start with the steps for Hadoop's single-node installations, as it's easy to understand and set up. This way, we can quickly perform simple operations using Hadoop MapReduce and the HDFS.

Prerequisites

Here are some prerequisites needed for Hadoop installations; make sure that the prerequisites are fulfilled to start working with Hadoop and YARN.

Platform

GNU/Unix is supported for Hadoop installation as a development as well as a production platform. The Windows platform is also supported for Hadoop installation, with some extra configurations. Now, we'll focus more on Linux-based platforms, as Hadoop is more widely used with these platforms and works more efficiently with Linux compared to Windows systems. Here are the steps for single-node Hadoop installation for Linux systems. If you want to install it on Windows, refer to the Hadoop wiki page for the installation steps.

Software
