## What is the purpose of the change Table hints will lost when they inside a view referenced by an external query, this is due to the upgrading of calcite-1.28 (affected by [CALCITE-4640](https://issues.apache.org/jira/browse/CALCITE-4640) which changed the default implementation of `SqlDialect` suppresses all table hints). We should use `AnsiSqlDialect` instead to reserve table hints. ## Brief change log use `AnsiSqlDialect` instead to reserve table hints ## Verifying this change add new case into existing `OptionsHintTest` ## 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?
