- If Java is not installed on your system then first install java under 'C:JAVA'
- Extract file Hadoop 2.8.0.tar.gz or Hadoop-2.8.0.zip and place under 'C:Hadoop-2.8.0'.

- Set the path JAVA_HOME Environment variable on windows 10(see Step 1,2,3 and 4 below).
- Next we set the Hadoop bin directory path and JAVA bin directory path.
Configuration
- Edit file C:/Hadoop-2.8.0/etc/hadoop/core-site.xml, paste below xml paragraph and save this file.
