   • Select the ‘Advanced’ tab, and then click ‘Environment Variables.’
   • Under ‘System variables,’ click ‘New.’
   • Enter HADOOP_HOME as the Variable name and the path to your Hadoop installation (e.g., C:\Hadoop) as the Variable value.
   • Click ‘OK’ to close all of the windows.

4. Add Hadoop’s Bin Directory to Path:

   • Go back to ‘Environment Variables.’
