    @arina-ielchiieva Thank your for the comments. There is some work that went 
into calcite to handle meaningful error messages. This is the checkin that has 
those changes.
    
https://github.com/apache/calcite/commit/5f9c019080c7231acaf3df80732d915351051d93#diff-0c11f3f4d738e3fa55968eb19f1c8050
    
    It reports following errors when a table cannot be resolved.
    {code}
    select empid from "hr".emps;
    Object 'EMPS' not found within 'hr'; did you mean 'emps'?
    !error
    {code}
    
    However, I think the error logic should be customized to particular 
software(in this case DRILL) so as to report semantically meaningful error 
messages. Drill knows more about the context and hence can provide more 
customized error messages to the end user.
