Stephen Chu created HADOOP-11502:
------------------------------------

             Summary: 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


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.
