Github user yjshen commented on the pull request: https://github.com/apache/flink/pull/1916#issuecomment-215334972 @twalthr, translate table API call to `SqlNode` and use `validator` in Calcite seems another reasonable solution, maybe it's hard to do `eager validation` as @fhueske proposed? Yes, I agree we should discuss which way is preferred solution :)
