thrift client(cross-language support, both tcp and http), a Java Database Connectivity(JDBC) interface over thrift, or an Open Database Connectivity (ODBC) interface over a JDBC-to-ODBC bridge to communicate Kyuubi delivers a beeline client, enabling a similar experience to Apache Hive use cases. Open Connections Replace the host and port with the actual ones you’ve got in the step of server startup for the 'jdbc:hive2://localhost:10009/' -n kentyao This may change depending on the engine share level you set. Close Connections Close the session between beeline and Kyuubi server by executing !quit, for example, > !quit
