   +1 for @squito 
   @hustfeiwang I don't think this PR does really help much, because if the fetch already has a retry logic(see RetryBlockFetcher). If what you mean probably a disk error, rewrite does not help much because they are under the same parent directory, and it's very likely an earlier writing failure would happen which directly causes FetchFailedException.
