We only support internal/external format in this usage. In this PR, we use LocalDateTime(the default external format of TimestampType) in TimestampMaxAggFunction/TimestampMinAggFunction to fix the ClassCastException. This PR **only fix release 1.9**. For release 1.10 or above, see https://github.com/apache/flink/pull/10722 ## Brief change log - b0bd11c use LocalDateTime in `TimestampMaxAggFunction` and `TimestampMinAggFunction` ## Verifying this change This change added tests ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): (yes / **no**) - The public API, i.e., is any changed class annotated with `@Public(Evolving)`: (yes / **no**) - The serializers: (yes / **no** / don't know) - The runtime per-record code paths (performance sensitive): (yes / **no** / don't know) - Anything that affects deployment or recovery: JobManager (and its components), Checkpointing, Yarn/Mesos, ZooKeeper: (yes / **no** / don't know) - The S3 file system connector: (yes / **no** / don't know) ## Documentation - Does this pull request introduce a new feature?
