    Description

      When looking at HADOOP-4526, I tried using sendError at line:53.

      FsckServlet.java
                                      _
           49     } catch (IOException ie) {
           50       StringUtils.stringifyException(ie);
           51       LOG.warn(ie);
           52       String errMsg = "Fsck on path " + pmap.get("path") + " failed.";
           53       response.sendError(HttpServletResponse.SC_GONE, errMsg);
           54       throw ie;
           55     }
      

      However, it always failed with

      And client wasn't seeing the error.
