Hi @Axel Schwanke ,
I just did a comparison between DBR 9.1 and DBR 10.1 and both have the same library version for Glue.
DBR 9.1 https://docs.databricks.com/release-notes/runtime/9.1.html
DBR 10.1 https://docs.databricks.com/release-notes/runtime/10.1.html
Are you using a high concurrency or standard cluster?
