Why create a new exception object if it is SemanticException. Previously if first is instance of SemanticException it was rethrown i.e. throw (SemanticException) first. But now we create a new CalciteSemanticException object. I think we should keep this case like it was i.e. just throw SemanticException as it is.

    If it is CalciteSemanticException we convert it to SemanticException for saving original cause(CalciteSubquerySemanticException or CalciteViewSemanticException). 
    If it is Semantic exceptin we just wrapped original message into CalciteSemanticException. If 
    we will do 
    throw new CalciteSemanticException(first) we will have redundant exception message such as 
    SemanticException : CalciteSemanticException : CalciteSubquerySemanticException.

    I didn't understand this. If it is CalciteSemanticException we convert it to CalciteSemancticException but if it is SemanticException we convert it to CalciteSemanticException? Why do we do that?

    Why should missing stats cause AST to reanalyze? This doesn't look correct.

    So basically if CBO fails due to some reason beside unsupported feature we will end up throwing semantic exception. This will cause the code to not try non-cbo in case of cbo failure. I don't think we want to do that.

Review request for hive, Ashutosh Chauhan and Vineet Garg.


Changes
-------

Rewrite the part of handling exception in CalcitePlanner.
1. If we got RuntimeException we just rethrow it.
2. If we got CalciteSemanticException with unsupported feature, we move to non-cbo analyzing.
3. If we got CalciteSemanticException w/o unsupported feature, we just rethrow it, wrapping it to new SemanticException(e.getMessage()), if we just wrap it, we will have redundant exception message with path of CalciteSemanticException.
Also, I've tested the original cause in the Hive CLI, and it throws expected error, that column reference not found.
