Github user HyukjinKwon commented on the issue: https://github.com/apache/spark/pull/17671 Also, there are many good tools Python debuggers, coverage and etc. I think providing a mechanism for such things is a great idea if possible but I doubt each support should be added while workarounds are relatively easy and possible. I personally don't like monkey-patch in general but it's good for working around in few specific cases and think it's fine if it is not excessive and is well understood. PySpark also uses it in few cases.
