@slachterman I am facing some issues with PySpark code and some places i see there are compatibility issues so i wanted to check if that is probably the issue. Even otherwise it is better to check these compatibility problems upfraont i guess. So i wanted to know some things. I am on 2.3.1 spark and 3.6.5 python, do we know if there is a compatibility issue with these? Do i upgrade to 3.7.0 (which i am planning) or downgrade to <3.6? What in your opinion is more sensible?
