---------------------------------
Status: Patch Available (was: Open)
> SPNEGO to Web UI fails with headers larger than 4KB
> ---------------------------------------------------
>
> Key: HADOOP-11502
> URL: https://issues.apache.org/jira/browse/HADOOP-11502
> Project: Hadoop Common
> Issue Type: Bug
> Components: security
> Affects Versions: 2.2.0
> Reporter: Stephen Chu
> Assignee: Stephen Chu
> Priority: Minor
> Attachments: HADOOP-11502.1.patch
>
>
> Thanks to [~bgooley] for reporting this:
> """
> 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.
