> Inside Fetcher.java there are a few cases where an error can happen and the
> corresponding map task is not marked as a fetch failure. One of these is if
> the Shuffle server returns a malformed result.
> MAPREDUCE-3992 makes this case a lot less common, but it is still possible.
> IF the shuffle handler always returns a malformed result, but a OK response
> the Fetcher will never stop trying to fetch those results.
