Subject [jira] [Created] (HADOOP-8830) org.apache.hadoop.security.authentication.server.AuthenticationFilter might be called twice, causing kerberos replay errors

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

             Summary: org.apache.hadoop.security.authentication.server.AuthenticationFilter
might be called twice, causing kerberos replay errors
                 Key: HADOOP-8830
                 URL: https://issues.apache.org/jira/browse/HADOOP-8830
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 2.0.1-alpha
            Reporter: Moritz Moeller


AuthenticationFilter.doFilter is called twice (not sure if that is intentional or not).

The second time it is called the ServletRequest is already authenticated, i.e. httpRequest.getRemoteUser()
returns non-null info.

If the kerberos authentication is triggered a second time it'll return a replay attack exception.

I solved this by adding a if (httpRequest.getRemoteUser() == null) at the very beginning of
doFilter.

Alternatively one can set an attribute on the request, or figure out why doFilter is called
twice.
