Alejandro Abdelnur updated HADOOP-8355:
---------------------------------------
Attachment: HADOOP-8355.patch
being a bit conservative, the AuthenticationFilter will not trust the
AuthenticationHandler to set the UNAUTHORIZED response when returning NULL and
it will set it itself (if happens twice is a NOP).
> SPNEGO filter throws/logs exception when authentication fails

> if the auth-token is NULL means the authenticator has not authenticated the
