title: How to run Hadoop on Cygwin with proper credentials to enable setting file permissions, etc.?
body: <p>I cannot change the permissions on files when I run Hadoop in Cygwin:</p>
  
  <pre><code>java.io.IOException: Failed to set permissions of path: \tmp\hadoop-James\mapred\staging\James-1143336710\.staging to 0700
  </code></pre>
  
  <p>From what I've gathered you can't really run Cygwin as root since Windows doesn't really have a notion of root (<a href="http://cygwin.com/ml/cygwin/2009-01/msg00338.html" rel="nofollow">reference</a>), and I've tried to run Cygwin as the Administrator user but this option isn't available to me when I right click on the Cygwin shortcut in Windows XP (I've also tried changing the Cygwin shortcut's properties to allow me to run as another user but that option is disabled).</p>
  
  <p>Can anyone advise me as to how I can get past this issue?  Thanks in advance for your help.</p>
