Pablo Langa bca9de6684 [SPARK-29922][SQL] SHOW FUNCTIONS should do multi-catalog resolution ... ### What changes were proposed in this pull request? Add ShowFunctionsStatement and make SHOW FUNCTIONS go through the same catalog/table resolution framework of v2 commands. We don’t have this methods in the catalog to implement an V2 command * catalog.listFunctions ### Why are the changes needed? It's important to make all the commands have the same table resolution behavior, to avoid confusing `SHOW FUNCTIONS LIKE namespace.function` ### Does this PR introduce any user-facing change? Yes. When running SHOW FUNCTIONS LIKE namespace.function Spark fails the command if the current catalog is set to a v2 catalog. ### How was this patch tested? Unit tests. Closes #26667 from planga82/feature/SPARK-29922_ShowFunctions_V2Catalog. Authored-by: Pablo Langa <soypab@gmail.com> Signed-off-by: Liang-Chi Hsieh <liangchi@uber.com>		2019-12-08 20:15:09 -08:00
