Hadoop Installation on Win 10 OS

Image
Setting the Hadoop files prior to Spark installation on Win 10: 1. Ensure that your JAVA_HOME is properly set. A recommended approach here is to navigate to the installed Java folder in Program Files and copy the contents into a new folder you can locate easily for eg:- C:\Projects\Java . 2. Create a user variable called JAVA_HOME and enter " C:\Projects\Java " 3. Add to the path system variable the following entry: " C:\Projects\Java\Bin; " 4. Create a HADOOP_HOME variable and specify the root path that contains all the Hadoop files for eg:- " C:\Projects\Hadoop " 5. Add to the path variable the bin location for your Hadoop repository: " C:\Projects\Hadoop\bin " <Keep  track of your Hadoop installs like C:\Projects\Hadoop\2_5_0\bin> 6. Once these variables are set, open command prompt as an administrator and run the following commands to ensure that everything is set correctly: A] java B] javac C] Hadoop D] Hadoop Version 7.
