> Union output partitioning should compare canonicalized attributes
> -----------------------------------------------------------------
>
> Key: SPARK-53550
> URL: https://issues.apache.org/jira/browse/SPARK-53550
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 4.1.0
> Reporter: L. C. Hsieh
> Assignee: L. C. Hsieh
> Priority: Major
> Labels: pull-request-available
>
> SPARK-52921 added the explicit output partitioning support for Union operator
> if its children have the same output partitioning.
> When comparing the output attributes from its children, currently it uses
> original attributes and it causes some errors when the attributes have some
> metadata or qualifier even they are semantically the same. We should compare
> them with their canonicalized forms.
