> Before this PR, will Spark write any temp files to the final shuffle file directory? In most cases, spark will manage its internal files as block files, including `ShuffleDataBlockId`, `ShuffleIndexBlockId`, `TempShuffleBlockId` and some other blocks. These block files are located by `hash(block name)` and the full block file path will be `localDirs(hash % localDirs.length)` / `(hash / localDirs.length) % subDirsPerLocalDir` / filename If the block files have the same hash code, then will be in the same directory. -- This is an automated message from the Apache Git Service.
