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.
