Arun C Murthy closed MAPREDUCE-4423. ------------------------------------ > Potential infinite fetching of map output > ----------------------------------------- > > Key: MAPREDUCE-4423 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4423 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv2 > Affects Versions: 0.23.3, 2.0.0-alpha, 3.0.0 > Reporter: Robert Joseph Evans > Assignee: Robert Joseph Evans > Priority: Critical > Fix For: 0.23.3, 2.0.2-alpha > > Attachments: MR-4423-branch-0.23.txt, MR-4423-trunk.txt, > MR-4423-trunk.txt, MR-4423.txt, MR-4423.txt, MR-4423.txt > > > 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. -- This message is automatically generated by JIRA.
