Configure Hadoop

Now that Hadoop has been unpacked, we are ready to configure it.

    1. Open a new Cygwin window and execute the following commands:
    cd hadoop-0.19.1
    cd conf
    explorer .

  2. Launch Eclipse.
  3. Bring up the 'conf' Explorer window opened in Step 2 and drag the file hadoop-site to the Eclipse main window.
  4. Insert the following lines between <configuration> and </configuration> tags.
