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. -- This message is automatically generated by JIRA.
