Subject [jira] [Updated] (HADOOP-15518) Authentication filter calling handler after request already authenticated
Date Thu, 07 Jun 2018 15:42:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-15518?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kevin Minder updated HADOOP-15518:
----------------------------------
    Description: The hadoop-auth AuthenticationFilter will invoke its handler even if a prior
successful authentication has occurred.  This primarily affects situations where multipole
authentication mechanism has been configured.  For example when core-site.xml's has hadoop.http.authentication.type
and yarn-site.xml has yarn.timeline-service.http-authentication.type 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.
