---------------------------------
Summary: pickle the exact globals of functions
Key: SPARK-3679
URL: https://issues.apache.org/jira/browse/SPARK-3679
Project: Spark
Issue Type: Bug
Components: PySpark
Reporter: Davies Liu

function.func_code.co_names has all the names used in the function, including
name of attributes. It will pickle some unnecessary globals if there is a
global having the same name with attribute (in co_names).
There is a regression introduced by PR 2114
