>> We can't get the information about the reason why the operator is considered as unresolved > This is a good point. CheckAnalysis provides better error messages for many cases, and the unresolved operator error is the last resort. I think we should provide better error message for this case as well. Yeah. It looks to be a bit tricky to generalize as any operator can make a decision on resolvable arbitrary. Probably the operator needs to have some method to provide additional information on `resolve` so that Analyzer can call to print out? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
