How about this: We make `SqlApiConf` the only place to deal with the active conf problem. It should use reflection to get the active `SQLConf` and set it as the getter. `SQLConf` should only access this new `SqlApiConfHelper` for config names. -- This is an automated message from the Apache Git Service.
