How to Install Hadoop on Windows 10 for a Single-node Setup?


If you are venturing into the world of Big Data, Apache Hadoop is an essential framework you should get acquainted with. Installing Hadoop on Windows 10 for a single-node setup is a popular choice for developers who wish to learn and experiment with Hadoop in a standalone capacity. This guide will walk you through the process of setting up Hadoop on Windows 10.

Prerequisites

Before you begin, you need to have the following:

  • Java JDK 8: Hadoop requires Java to be installed on your system. You can download it from Oracle’s official website.
  • Windows 10 Operating System: Ensure you have administrative privileges to install required components.

Step-by-Step Guide to Install Hadoop on Windows 10

Step 1: Install Java JDK

  1. Download Java JDK 8 from the Oracle website.

  2. Install the JDK by following the on-screen instructions.

  3. Set the JAVA_HOME environment variable to the JDK folder. Navigate to Control Panel -> System and Security -> System -> Advanced System Settings -> Environment Variables. Add a new system variable with:

    Variable name: JAVA_HOME
    Variable value: C:\Program Files\Java\jdk1.8.0_xx
  4. Update the Path variable by adding %JAVA_HOME%\bin.

Step 2: Download Hadoop

  1. Download a stable release of Hadoop from the Apache Hadoop Releases page.
  2. Extract the downloaded Hadoop package to a directory of your choice, for instance C:\hadoop.

Step 3: Configure Hadoop

  1. Set the HADOOP_HOME environment variable. Similar to setting JAVA_HOME, navigate to Environment Variables and add:

    Variable name: HADOOP_HOME
    Variable value: C:\hadoop
  2. Add %HADOOP_HOME%\bin to the Path environment variable.

Step 4: Configure Hadoop Files

Within the Hadoop directory (C:\hadoop\etc\hadoop), edit the following configuration files:

  • core-site.xml: Define default filesystem URL.

    <configuration>
      <property>
        <name>fs.defaultFS</name>
        <value>hdfs://localhost:9000</value>
      </property>
    </configuration>
  • hdfs-site.xml: Configure HDFS replication factor.

    <configuration>
      <property>
        <name>dfs.replication</name>
        <value>1</value>
      </property>
    </configuration>
  • mapred-site.xml: Suggest job tracker.

    <configuration>
      <property>
        <name>mapreduce.framework.name</name>
        <value>yarn</value>
      </property>
    </configuration>
  • yarn-site.xml: Configure yarn daemon.

    <configuration>
      <property>
        <name>yarn.nodemanager.aux-services</name>
        <value>mapreduce_shuffle</value>
      </property>
    </configuration>

Step 5: Format the Hadoop Namenode

Run the following command in the Command Prompt:

hdfs namenode -format

Step 6: Start Hadoop Services

Launch the following commands to start Hadoop services:

start-dfs.cmd
start-yarn.cmd

Django Tuning

Congratulations! You have set up a Hadoop single-node cluster on Windows 10. You can now start running Hadoop commands and begin processing big data on your local machine.
