> 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.
