> 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.
