To start with, set environmental variables in the ~/.bashrc file. Here, we will be configuring Hadoop in Pseudo-Distributed mode.

Fully Distributed Mode вЂ“ It is an actual multinode cluster ranging from few nodes to extremely large cluster.

Pseudo-Distributed Mode вЂ“ Each Hadoop daemon runs in a separate process.

Local (Standalone) Mode вЂ“ It runs as a single java process.

You can visit Apache Hadoop page to download the latest Hadoop package, or you can issue the following command in terminal to download Hadoop v3.2.0.

HADOOP INSTALLATION ON WINDOWS 7 INSTALL

$ ssh 127.0.0.1 Install Apache Hadoop Download Hadoop If you are doing ssh for the first time, type yes to add RSA keys to known hosts. Verify the passwordless communication to the local system. $ cat ~/.ssh/id_rsa.pub > ~/.ssh/authorized_keys

Create an ssh key using the following commands. Once you created a user, configure passwordless ssh to the local system. # useradd -m -d /home/hadoop -s /bin/bash hadoop So, create a user named hadoop and set a password. It is recommended to create a regular user to configure and run Apache Hadoop. OpenJDK 64-Bit Server VM (build 25.212-b04, mixed mode) Create Hadoop user & Enable Passwordless Authentication OpenJDK Runtime Environment (build 1.8.0_212-b04) Here, for this demo, I will be installing OpenJDK 8.

PrerequisitesДЄpache Hadoop requires Java version 8 only. This guide should also work on Ubuntu 16.04. This guide will help you to install Apache Hadoop on CentOS 7, Ubuntu 18.04 & Debian 9.

Hadoop MapReduce вЂ“ is a framework for large-scale data processing.

Hadoop YARN вЂ“ It manages resources on compute clusters and using them for scheduling userвЂ™s applications.

Hadoop Distributed File System (HDFS) вЂ“ is a Java-based distributed file-system that stores data, providing very high-throughput to the application.

Hadoop Common вЂ“ It contains a common set of libraries and utilities that support other Hadoop modules.

Hadoop framework consists of following modules, Rather than rely on hardware high availability, Hadoop modules are designed to detect and handle the failure at the application layer, so gives you high-available service.
