The exit() builtin is only for interactive use. applications should use sys.exit(). ## What changes were proposed in this pull request? All usage of the builtin `exit()` function is replaced by `sys.exit()`. ## How was this patch tested? I ran `python/run-tests`. Please review http://spark.apache.org/contributing.html before opening a pull request. Author: Benjamin Peterson <benjamin@python.org> Closes #20682 from benjaminp/sys-exit.
