Piotr Nowojski commented on FLINK-23180:
----------------------------------------

[~wind_ljy], I think you are right, it doesn't make sense to create unused 
directories. If checkpointing is disabled, we should skip it. I would still 
suggest to keep it initialised eagerly, at the very least in order to fail 
fast. I'm not sure how easy/difficult would it be to implement it, as I don't 
remember the code.

Would you like to work on this issue [~wind_ljy]?
