      Description

      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.
