The benefit is: the path calculating is stateless and it's cheap to do. We can even do it in different JVMs. But not sure if we leverage this property in Spark. cc @vanzin @squito yes, maybe add blacklist is enough for this problem. I will check how ExternalShuffleService use `deterministic mapping from filename to its path`.
