> A lock file is used to ensure multiple executors running on the same machine
> don't download the same file concurrently. Spark never closes these lock
> files (we release the lock, but releasing the lock does not close the
> underlying file). In theory, if an executor fetched a large number of files,
> this could eventually lead to an issue with too many open files.
