Ning Zhang commented on HIVE-2525:
----------------------------------
I agree with Namit. The right approach is to throw a better error message in
the parser rather than adding a special checking for a specific negative case.
There are a lot of such negative cases. If we add checks for all of them, it
becomes cumbersome and redundant in terms of parser's functionality.
> Introduce proper error messages, when explain fails on commands that
> otherwise could be succesful (commands that are not analyzed by Semantic
> Analyzer)
