--------------------------------

Hi [~elgoiri], i find that there is no fsck on namenode WebUI. And namenode's 
httpserver2 code is following (trunk branch)
{code}
  /**
   * Add default servlets.
   */
  protected void addDefaultServlets() {
    // set up default servlets
    addServlet("stacks", "/stacks", StackServlet.class);
    addServlet("logLevel", "/logLevel", LogLevel.Servlet.class);
    addServlet("jmx", "/jmx", JMXJsonServlet.class);
    addServlet("conf", "/conf", ConfServlet.class);
  }
{code}
Maybe we do not need fsck on WebUI?
