   > Good idea, can you list what should do in issue?
   
   Yes. Before starting a scaling job, we should do these things:
   1. check the connection and user's privileges of the source's datasource;
   2. check the connection and user's privileges of the target's datasource.
   
   If all checks are ok, then start the job, otherwise, we should through the exception and the job start failed.
