Namenode couldn't execute as Windows service

                 Key: HADOOP-3508
                 URL: https://issues.apache.org/jira/browse/HADOOP-3508
             Project: Hadoop Core
          Issue Type: Improvement
          Components: dfs
    Affects Versions: 0.17.0
         Environment: Windows XP, Windows 2003 Server
            Reporter: NOMURA Yoshihide

The Hadoop Namenode couldn't execute as Windows service,
because UnixUserGroupInformation#getUnixUserName() throws IOException.
The 'whoami' command output is 'nt authority\system' in default Windows service,
so I suggest to change the method like follows:

  static String getUnixUserName() throws IOException {
    String[] result = executeShellCommand(
        new String[]{Shell.USER_NAME_COMMAND});
    if (Shell.WINDOWS) {
    	return toString(result);
    } else if (result.length!=1) {
      throw new IOException("Expect one token as the result of " + 
          Shell.USER_NAME_COMMAND + ": " + toString(result));
    return result[0];
