I am using com.mysql.jdbc.Driver.8.X.XX and it throws an error about that CEST is an unrecognized timezone, now I have resolved that issue for hive, oozie by using jdbc:mysql://"myhost":3306/hive?serverTimezone=UTC as a connection string.
When I test the database connection it returns "ok", but when I start the service it returns:

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.
SQLException : SQL state: 01S00 java.sql.SQLException: The server time zone value 'CEST' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the 'serverTimezone' configuration property) to use a more specifc time zone value if you want to utilize time zone support. ErrorCode: 0

So I think Ranger does not use my connection string but a default one.
