How to run any arbitrary code - which is not related to RDDs - on all of the executors.
lets say I want to save the date into a file on all drivers and executors periodically
Files.write(Paths.get("file.txt"), ZoneddateTime.now().toString().getBytes(StandardCharsets.UTF_8))
This will do it on the driver only.
edit:
I know that I can send files to the executors at spark-submit time, but I want to create/update files runtime.
