> Key: TEZ-2041
> URL: https://issues.apache.org/jira/browse/TEZ-2041
> Project: Apache Tez
> Issue Type: Bug
> Components: UI
> Reporter: Jeff Zhang
> Priority: Minor
> Attachments: task.png
>
>
> There's one special case that one task may be associated with 2 succeeded
> task_attempt when recovery happens. If the first succeeded task attempt can
> not be recovered. Another task attempt will be scheduled. So in this case,
> there will be 2 succeeded task attempts for the same task. It may confuse
> users on tez-ui, maybe could provide extra info about recovery on tez-ui.
> This also need extra info in the history event.
