Aihua Xu commented on HIVE-13991:
---------------------------------
OK. That makes more sense. So will you change the code to differentiate the
calls based on them, like from genResolvedParseTree() you will do merge, or
you keep the same code just with a better explanation? Maybe find a more
reasonable way to set mergeIsDirect?
> Union All on view fail with no valid permission on underneath table
