Unpack Hadoop Installation

The next step is to unpack the downloaded and copied package.

To unpack the package follow these steps:

1. 1. Open a new Cygwin window.
   2. After the new Cygwin window appears, execute the following command:
      tar -xzf hadoop-0.19.1.tar.gz
      This will start unpacking the Hadoop distribution. After several minutes you should see a new Cygwin prompt again as shown in the screenshot below:
   3. When you see the new prompt, execute the following command:
      ls -l
      This command will list the contents of your home directory. You should see a newly created directory called hadoop-0.19.1 
   4. Next execute the following commands:
      cd hadoop-0.19.1
      ls -l
      
      If you get output similar to the following, everything was unpacked correctly and you can go to the next step.
