* You can create an `auxlib` folder under the root directory of Hive, and copy
`flink-table-store-hive-connector-{{< version >}}.jar` into `auxlib`.
* You can also copy this jar to a path accessible by Hive, then use `add jar

store support in Hive. Note that this method is not recommended. If you're
