> Speculative attempt scheduling should be aborted when Task has completed

> Key: TEZ-4062
> URL: https://issues.apache.org/jira/browse/TEZ-4062
> Project: Apache Tez
> Issue Type: Bug
> Reporter: Yingda Chen
> Assignee: Ying Han
> Priority: Major
> Attachments: TEZ-4062.001.patch
>
> Time Spent: 1h 10m
> Remaining Estimate: 0h
>
> In RedundantScheduleTransition (inside TaskImpl), we try to find the oldest
> running attempt and use it as the causual attempt when doing
> "addAndScheduleAttempt".
>
> However, the task may have completed at this moment, i.e., the task attempt
> that was considered running and long-tailed by speculator is now completed.
> In this case, we may not be able to find any unfinished attempt, which will
> lead to NPE in following logic (even without NPE, it still makes no sense to
> proceed with scheduling speculative attempt anyway)
