title: Hadoop good example of production implementation
body: <p>I hear lot about Hadoop but when it comes for defining what it is i get confused. Because definition defers form point to point.</p>
  
  <p>Is Hadoop something that serves files from server to client?</p>
  
  <p>Ex: If we implement Hadoop for a <strong>MAILDIR</strong> where emails are stored, Can Hadoop help in accessing the emails and serving it to client in super fast speed? Is this how it can be used?</p>
  
  <p>Can you tell me in <code>simple words</code> what is Hadoop and its uses?</p>
