> Key: MAPREDUCE-4330

> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Bikas Saha
> Assignee: omkar vinit joshi
>
> 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.
