---------------------------------------------

[~daryn], have you had a chance to think about this? Does seems reasonable to you to close it as invalid?

> As mentioned in HADOOP-10453, the JDK automatically does a SPNEGO handshake when opening a connection with a URL within a Kerberos login context, there is no need to do the SPNEGO handshake in the {{KerberosAuthenticator}}, simply extract the auth token (hadoop-auth cookie) and do the fallback if necessary.
