### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) ### Search before asking - [X] I have searched in the [issues](https://github.com/apache/kyuubi/issues?q=is%3Aissue) and found no similar issues. ### What would you like to be improved? When the kyuubi.engine.jdbc.connection.url specified database does not exist, the Client will receive a **java.sql.SQLSyntaxErrorException: Unknown database 'ddddd'**, but the JDBCEngine process does not exit. Subsequent Client connections will still be sent to the JDBCEngine, but will not be successful, even if the change to the correct database name, because JDBCEngine will only read the parameters passed in when the process startedThis causes the JDBCEngine to be unavailable until the timeout is destroyed. My beeline parameters ``` ./beeline -u 'jdbc:kyuubi://localhost:10009/default;# kyuubi.engine.type=jdbc;kyuubi.engine.jdbc.connection.url=jdbc:mysql://localhost:13306/ddddd; kyuubi.engine.jdbc.connection.user=root; kyuubi.engine.jdbc.connection.password=root; kyuubi.engine.jdbc.driver.class=com.mysql.cj.jdbc.Driver; kyuubi.engine.jdbc.extra.classpath=/Users/hrh/.m2/repository/mysql/mysql-connector-java/8.0.13/mysql-connector-java-8.0.13.jar; kyuubi.engine.jdbc.connection.provider=DorisConnectionProvider; kyuubi.engine.jdbc.type=doris' ``` <img width="2222" alt="image" src="https://github.com/apache/kyuubi/assets/41908930/6d7b3d9b-5a5f-494e-b191-1806b0f4ad7f";> ### How should we improve? Can we determine at JDBCSession.close that if the sessionConnection is not initialized successfully, the process exits https://github.com/apache/kyuubi/blob/master/externals/kyuubi-jdbc-engine/src/main/scala/org/apache/kyuubi/engine/jdbc/session/JdbcSessionImpl.scala#L76 ### Are you willing to submit PR? - [X] Yes.
