Description

 public static void fetchServiceTicket(URL remoteHost) throws IOException {
    if(!UserGroupInformation.isSecurityEnabled())
      return;
    
    String serviceName = "host/" + remoteHost.getHost();

the hostname should be converted to lower case. Saw this in branch 1, will look at trunk and update the bug accordingly.
