> Local or temp shuffle files are initialized without checking because the
> getFile method in DiskBlockManager probably return an existing subdirectory.
> Sometimes, when a disk failure occurs, those files may become inaccessible
> and throw FileNotFoundException later, which may fail the entire task. Task
> re-running is a bit heavy for these errors, we may give another or more disks
> a try at least.
