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.
