 * @param message value not used.
 * @param headers value not used.
 * @return response code.
 */
@DELETE
public Response deleteNoBody(final byte[] message,
    final @Context UriInfo uriInfo, final @Context HttpHeaders headers) {
  if (LOG.isDebugEnabled()) {
    LOG.debug("DELETE " + uriInfo.getAbsolutePath());
  }
  if (servlet.isReadOnly()) {
    servlet.getMetrics().incrementFailedDeleteRequests(1);
    return Response.status(Response.Status.FORBIDDEN).type(MIMETYPE_TEXT)
        .entity("Forbidden" + CRLF).build();
  }

  try{
    Admin admin = servlet.getAdmin();
    if (!doesNamespaceExist(admin, namespace)){
      return Response.status(Response.Status.NOT_FOUND).type(MIMETYPE_TEXT).
          entity("Namespace '" + namespace + "' does not exists.  Cannot " +
          "drop namespace.").build();
