> Key: MAPREDUCE-4330
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4330
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 0.23.1
> Reporter: Bikas Saha
> Assignee: Omkar Vinit Joshi
> Attachments: MAPREDUCE-4330-20130415.1.patch,
> MAPREDUCE-4330-20130415.patch, MAPREDUCE-4330-21032013.1.patch,
> MAPREDUCE-4330-21032013.patch
>
>
> The previously completed attempt is removed from
> successAttemptCompletionEventNoMap and marked OBSOLETE.
> After that, if the newly completed attempt is successful then it is added to
> the successAttemptCompletionEventNoMap.
> This seems wrong because the newly completed attempt could be failed and thus
> there is no need to invalidate the successful attempt.
> One error case would be when a speculative attempt completes with
> killed/failed after the successful version has completed.
