      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.
