Hadoop has many configuration files, and we need to edit them depends on the cluster modes we set up (Pseudo-Distributed). $ source ~/.bashrc Modify Configuration filesĮdit the Hadoop environmental file. export JAVA_HOME= /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.7_6.x86_64/jre # Change it according to your systemĮxport HADOOP_HOME= /home/hadoop/hadoop # Change it according to your systemĮxport HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/nativeĮxport PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/binĪpply environmental variables to the current session. To start with, set environmental variables in the ~/.bashrc file. Here, we will be configuring Hadoop in Pseudo-Distributed mode.

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

Pseudo-Distributed Mode – Each Hadoop daemon runs in a separate process.Local (Standalone) Mode – It runs as a single java process.

$ 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.

READ: How To Install Oracle Java on Debian 9 READ: How To Install Oracle Java on Ubuntu 18.04 READ: How To Install Oracle Java on CentOS 7 / RHEL 7 So, you can choose to install either OpenJDK or Oracle JDK. PrerequisitesĪpache 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 – is a framework for large-scale data processing.

Hadoop YARN – It manages resources on compute clusters and using them for scheduling user’s applications.

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

Hadoop Common – 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.

Apache Hadoop is an open-source software framework written in Java for distributed storage and distributed process, and it handles the very large size of data sets by distributing it across computer clusters.
