-------------------------------------
Summary: Spark 3 / Cats 2.2.0 classpath issue
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
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.
{code:java}
