> In ASTConverter, there is some logic to invert join inputs so the logic to
> merge joins in SemanticAnalyzer kicks in.
> https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/optimizer/calcite/translator/ASTConverter.java#L407
> There is a bug because inputs are swapped but the schema is not.
