> When SSL and Kerberos Authentication is enabled for hadoop web GUIs, if the header is
over 4KB in size, the browser shows a blank page.
> Browser dev tools show that a 413 full head error is returned as a response from Jetty.
> It seems that in HADOOP-8816, we only addressed non-ssl ports by setting ret.setHeaderBufferSize(1024*64);
> However, with SSL enabled, we use SslSocketConnector() but don't set the HeaderBufferSize.
I think this is why we are failing at the default Jetty max header buffer size of 4KB.
