I want to upgrade Apache IoTDB Version 1.0.1 to Version 1.2. After replacing the lib files, I can successfully startup IoTDB, but when executing show cluster details command, an error is reported: ERROR o.a.i.d.u.ErrorHandlingUtils:61 - Status code: INTERNAL_SERVER_ERROR(305), operation: "show cluster details" . executeStatement failed. In my upgrading process, I first executed sh stop-stand-alone.sh, then replaced lib files and executed sh start-stand-alone.sh, so all the ConfigNodes should be stopped when upgrading. Therefore, anyone knows why the IoTDB cluster execution went wrong?
You have to upgrade from Apache IoTDB Version 1.0.X to Version 1.1 first, and then to Version 1.2. The upgrading way from 1.0.X to 1.1 is the same way you mentioned, by changing lib files. See if in this way your problem will be solved.
