How to Setup a Hadoop Cluster on Your Windows Machine

Setting up Hadoop is an easy task with the right guide. This is where our experts step in. Follow this guide, and you’ll have Hadoop up and running on your system in no time.

1. First, we have to install Java on the system. So, go to this link and download the latest Java JDK.
2. Then, run the installer we downloaded and follow the prompts to complete the installation.
3. Next, go to the Apache Hadoop website and download the latest stable release.
4. Then, unzip the downloaded file.
5. Now, configure the environment variables so that the system knows where Hadoop is installed:
   1. First, search for “Edit the system environment variables” in the Start menu and open it.
   2. Then, click the “Environment Variables” button.
   3. Next, click “New” under “System variables”.
   4. Now, set the **Variable name** to `HADOOP_HOME`.
   5. Furthermore, set the **Variable value** to the path of the Hadoop folder.
   6. Then, find the “Path” variable in the System variables list and click “Edit”.
   7. Next, click “New” and add `%HADOOP_HOME%\bin` to the path.
   8. Finally, click “OK” to save and close all windows.

How to Configure Hadoop

1. First, go to the `etc\hadoop` folder in the Hadoop installation directory.
2. Then, open `core-site.xml` file and add the following:

   
3. Now, open `hdfs-site.xml` and add:

   
4. Then, create and Edit mapred-site.xml. This is done by copying `mapred-site.xml.template` to `mapred-site.xml`.
5. Open `mapred-site.xml` and add:

   

   Save the file and exit.
6. Then, go to the `bin` folder in the Hadoop installation directory and run:

   hadoop namenode -format
7. Now, start all Hadoop services to get the cluster running by going to the `sbin` folder in the Hadoop installation directory. Then, run this command:

   start-all.cmd

   Wait a few minutes for all services to start up.

You can check if everything is running smoothly by going to `http://localhost:9870/` and checking the Hadoop NameNode web interface with information about your cluster.
