This PR bases on https://github.com/apache/flink/pull/8639 I will document the exact type mappings between Flink and Hive later on. ## Brief change log - added mapping for BinaryType, VarBinaryType, CharType, VarCharType, and DecimalType in HiveTypeUtil - added CharType, VarCharType, and DecimalType existing `testDataTypes()` unit test - added `testNonExactlyMatchedDataTypes()` for BinaryType, VarBinaryType ## Verifying this change This change added tests and can be verified as follows: - added CharType, VarCharType, and DecimalType existing `testDataTypes()` unit test - added `testNonExactlyMatchedDataTypes()` for BinaryType, VarBinaryType ## 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, Yarn/Mesos, ZooKeeper: (no) - The S3 file system connector: (no) ## Documentation - Does this pull request introduce a new feature? (yes ) - If yes, how is the feature documented? (docs) I will document the exact type mappings between Flink and Hive later on.
