gustavodemorais opened a new pull request, #28834: URL: https://github.com/apache/flink/pull/28834
## What is the purpose of the change Using a non-orderable type (MAP, MULTISET, VARIANT, BITMAP, TIMESTAMP_WITH_TIME_ZONE) as a sort, grouping, or join key threw a raw UnsupportedOperationException from comparator code generation. This changes it to a ValidationException with a clearer, actionable message, since it is invalid user SQL rather than an internal error. ## Brief change log - Throw ValidationException instead of UnsupportedOperationException for non-orderable types in GenerateUtils.generateCompare, with a message that names the type and the remedy. - Update CalcITCase and BitmapSemanticTest to expect ValidationException and the new message. - Remove the now-unused UnsupportedOperationException allowance from FailingSqlTestStep. ## Verifying this change - CalcITCase - BitmapSemanticTest ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (no) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (no) - The serializers: (no) - The runtime per-record code paths (performance sensitive): (no) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Kubernetes/Yarn, ZooKeeper: (no) - The S3 file system connector: (no) ## Documentation - Does this pull request introduce a new feature?
