> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.3.0, 1.3.1, 1.4.0
> Reporter: Antonio Jesus Navarro
>
> The AttributeReference "equals" method only accept as different objects with different name, expression id or dataType. With this behavior when I tried to do a "transformExpressionsDown" and try to transform qualifiers inside "AttributeReferences", these objects are not replaced, because the transformer considers them equal.
> I propose to add to the "equals" method this variables:
> name, dataType, nullable, metadata, epxrId, qualifiers
