Review Comment:
Option 3: Adding the configuration
`fluss.hadoop.hadoop.security.authentication` does not work. The root cause is
that when initializing the `UserGroupInformation` class, it uses an empty
Configuration instance instead of our Fluss-specific Hadoop configuration.
I noticed that Flink includes a security module which is responsible for
setting the configuration of `UserGroupInformation` — this might be relevant to
our issue. For reference, see the following link:
https://github.com/apache/flink/blob/78136133fbec4ca145dec66d4bc0c324c8e16d82/flink-runtime/src/main/java/org/apache/flink/runtime/security/modules/HadoopModule.java#L68-L70
