    Hi @vundela , thanks for your PR.  I was able to reproduce your issue, but I think your fix here uses too broad of lock, since the shared resource is the SparkContext pickle registry and needs to be locked only while the python command is being pickled.  Please see #18695 and if you wouldn't mind checking if that solves your issue as well.  Thanks!
