The "method not supported" error usually occurs when PreparedStatement is not supported by the Hive JDBC Driver that is establishing the connection.
If I want to connect to Hive Server, I would choose the necessary **Database Adapter** and download the JDBC Driver from the Vendor's official site as Denodo **does** **not** provide the Hive [**JDBC Driver**](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/appendix/supported_jdbc_data_sources/supported_jdbc_data_sources#supported-jdbc-data-sources) for connecting to Hive. In case I encounter "method not supported" error when connecting to Hive, I would check if the downloaded Hive JDBC Driver supports PreparedStatement.
If you have more questions and you are a user with a valid support account, then I would suggest you raise a support case in the [**Denodo Support Site**](https://support.denodo.com/) with more detailed information.
Hope this helps!
