> In HDFS-7279 the Netty server in DN proxies all servlet requests to the local Jetty instance.
> The Jetty server is configured incorrectly so that it always uses {{HTTP/locahost@REALM}}
to authenticate spnego requests. As a result, servlets like JMX are no longer accessible in
secure deployments.
