Bikas Saha created MAPREDUCE-4330: ------------------------------------- Summary: TaskAttemptCompletedEventTransition invalidates previously successful attempt without checking if the newly completed attempt is successful Key: MAPREDUCE-4330 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4330 Project: Hadoop Map/Reduce Issue Type: Bug Reporter: Bikas Saha Assignee: Bikas Saha
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. -- This message is automatically generated by JIRA.
