Sunil Govindan commented on HADOOP-15518:
-----------------------------------------
[~eyang] This latest issue (Problem accessing
/proxy/application_1528498597648_0001/) is a different problem, correct?
bq.If multiple AuthenticationFilters are configured, and service principal
names are different
Are you mentioning a case where AuthenticationFilter is added multiple time
(like Spnego Filter and authentication) but will use different keytab?

> The hadoop-auth AuthenticationFilter will invoke its handler even if a prior
> successful authentication has occurred in the current request. This
> primarily affects situations where multiple authentication mechanism has been
> configured. For example when core-site.xml's has
> hadoop.http.authentication.type=kerberos and yarn-site.xml has
> yarn.timeline-service.http-authentication.type=kerberos the result is an
> attempt to perform two Kerberos authentications for the same request. This
> in turn results in Kerberos triggering a replay attack detection. The
> javadocs for AuthenticationHandler
> ([https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-auth/src/main/java/org/apache/hadoop/security/authentication/server/AuthenticationHandler.java)]
> indicate for the authenticate method that
> {quote}This method is invoked by the AuthenticationFilter only if the HTTP
> client request is not yet authenticated.
> {quote}
> This does not appear to be the case in practice.
> I've create a patch and tested on a limited number of functional use cases
> (e.g. the timeline-service issue noted above). If there is general agreement
> that the change is valid I'll add unit tests to the patch.
