Contributor guide
Research direction
The issue reports separate failures for Flink YARN session and application modes but provides no server or engine logs, configuration, files, or tests. Start by reproducing both modes on Kyuubi 1.7.1 or later and inspect the reported PLAIN mechanism and InvalidACL errors. Done means both Kerberos-enabled modes run successfully without those exceptions.
