> GetJournalEditServlet fails to authorize valid Kerberos request
> ---------------------------------------------------------------
>
> Key: HDFS-16686
> URL: https://issues.apache.org/jira/browse/HDFS-16686
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: journal-node
> Environment: Running in Kubernetes using Java 11 in an HA
> configuration. JournalNodes run on separate pods and have their own Kerberos
> principal "jn/<hostname>@<realm>".
> Reporter: Steve Vaughan
> Assignee: Steve Vaughan
> Priority: Major
> Labels: pull-request-available
>
> GetJournalEditServlet uses request.getRemoteuser() to determine the
> remoteShortName for Kerberos authorization, which fails to match when the
> JournalNode uses its own Kerberos principal (e.g. jn/<hostname>@<realm>).
> This can be fixed by using the UserGroupInformation provided by the base
> DfsServlet class using the getUGI(request, conf) call.
