>                 Key: SPARK-33077
>                 URL: https://issues.apache.org/jira/browse/SPARK-33077
>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Core, Spark Shell
>    Affects Versions: 3.0.1
>            Reporter: Sami Dalouche
>            Priority: Major
>
> A small project with minimal dependencies as well as instructions on how to reproduce the issue is available at:
> [https://github.com/samidalouche/spark3-cats220]
> Executing this code works fine with cats 2.1.1 but fails with cats 2.2.0, which is quite surprising since the spark and cats dependencies are pretty much distinct from each other.
