> In {{HttpServer2#hasAdministratorAccess}}, it uses
> `hadoop.security.authorization` to detect whether HTTP is authenticated.
> It's not correct, because enabling Kerberos and HTTP SPNEGO are two steps. If
> Kerberos is enabled while HTTP SPNEGO is not, some links cannot be accessed,
> such as "/logs", and it will return error message as below:
> {quote}
> HTTP ERROR 403
> Problem accessing /logs/. Reason:
> User dr.who is unauthorized to access this page.
> {quote}
> We should make sure {{HttpServletRequest#getAuthType}} is not null before we
> invoke {{HttpServer2#hasAdministratorAccess}}.
> {{getAuthType}} means to get the authorization scheme of this request
