Github user aljoscha commented on the issue: https://github.com/apache/flink/pull/6377 @zentol I addressed most of your comments. I now added a test in there that verifies the job fails if we don't set a keytab. I'm not running with different Hadoop. It might work but I'm basically setting up a hadoop cluster in docker and I don't know if this is similar enough (or exactly the same, for my purposes) between the versions. @dawidwys Thanks for the thorough comments, I'll go through them next!
