@squito There are few IOExceptions occur when creating inputStream. But I think it is a complete mechanism to refetch these remote corrupt block just like when the shuffleFetcherItertor detect that the block is corrupt later. If it is just as a fetchFailed to deal with, it would remove the relative mapout put and recompute previous relative tasks, which is expensive in a multi-stage job especially.
