JspHeler.getUGI assumes user is KerbSSL'ed authed, which may not be true
------------------------------------------------------------------------

                 Key: HDFS-1018
                 URL: https://issues.apache.org/jira/browse/HDFS-1018
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Jakob Homan


As identified in HDFS-1017, the UGI helper function defaults to Kerberos SSL as the final
possible authentication method for an authenticated user.  However, this may not be true if
another filter is used to authenticate users, which is provided for.  We should create another
value to signify if users were actually Kerbed auth or done another way.  Kerberos auth can
be verified by checking for instanceof KerberosPrincipal in the helper.
