# How to Install Hadoop on Windows 10 for a Single-Node Setup

Setting up Hadoop on Windows 10 for a single-node configuration can be straightforward with the right guidance.

Hadoop is an open-source software framework for storing data and running applications on clusters of commodity hardware. Follow these steps to ensure a successful Hadoop installation on your Windows 10 machine.

Prerequisites

Before you start, ensure your system meets the following requirements:

• Windows 10 operating system.
• Java Development Kit (JDK) installed (version 8 or later). Ensure JAVA_HOME is set in environment variables.
• Adequate disk space to store Hadoop files.

Step-by-Step Hadoop Installation

1. Download Hadoop:

   • Download the binary from the Hadoop releases page. It's recommended to get the stable version. Extract the files to a suitable location (e.g., C:\hadoop).

2. Configure Environment Variables:

   • Add a new environment variable HADOOP_HOME and set it to the path where you extracted Hadoop (C:\hadoop).
   • Edit the Path variable and add %HADOOP_HOME%\bin and %HADOOP_HOME%\sbin.

3. Set Up Hadoop Configuration Files:

   • Navigate to the Hadoop etc\hadoop directory to modify these files:

     • core-site.xml:

       Add configuration for the default filesystem:

       <configuration>
           <property>
               <name>fs.defaultFS</name>
               <value>hdfs://localhost:9000</value>
           </property>
       </configuration>
       

     • hdfs-site.xml:

       Set the replication factor to 1 for a single-node setup:

       <configuration>
           <property>
               <name>dfs.replication</name>
               <value>1</value>
           </property>
       </configuration>
       

     • mapred-site.xml:

       Make sure mapred-site.xml reflects the following:

       <configuration>
           <property>
               <name>mapreduce.framework.name</name>
               <value>yarn</value>
           </property>
       </configuration>
       

     • yarn-site.xml:

       Add the following configurations to enable resource management:

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

4. Set Up Hadoop Directory:

   • Create a directory to store the NameNode and DataNode data:

     mkdir C:\hadoop\data\namenode
     mkdir C:\hadoop\data\datanode
     

5. Format the NameNode:

   • Open a command prompt with administrator rights, navigate to the Hadoop bin directory, and execute:

     hdfs namenode -format
     

6. Start Hadoop Daemons:

   • Launch the the Hadoop Daemons via start-all.cmd script available in %HADOOP_HOME%\sbin.

7. Verify the Installation:

   • To ensure the Hadoop services are running, access http://localhost:9870/ to view the NameNode status.

Troubleshooting and Additional Resources

1. Common Setup Issues:

   • You may encounter warnings or errors during setup. Refer to this guide on fixing warnings in Hadoop installation for solutions.

2. Further Integrations:

   • For advanced integrations, such as using MATLAB with Hadoop, see how to integrate MATLAB with Hadoop.

3. Additional Tutorials:

   • For a detailed explanation of configuring HDFS, refer to how to config HDFS in Hadoop.
