Hyukjin Kwon commented on SPARK-47288:
--------------------------------------
I agree in principle but my concern is more about backward compatibility.
> DataType __repr__ change breaks datatype checking (anit-)pattern
> ----------------------------------------------------------------

> Key: SPARK-47288
> URL: https://issues.apache.org/jira/browse/SPARK-47288
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.4.1
> Reporter: Ted Chester Jenks
> Priority: Major
>
> This pr: [https://github.com/apache/spark/pull/34320]
> Made reprs for datatype eval-able. This is kind of nice, but we have a ton of
> users doing stuff like:
>
> {code:java}
> if str(data_type) == "StringType":
> ...
> {code}
>
> Which breaks.
>
> What would people think of adding a __str__ to the base class that returns
> the old behaviour so we can have the best of both worlds.
