> Key: SPARK-10530
> URL: https://issues.apache.org/jira/browse/SPARK-10530
> Project: Spark
> Issue Type: Improvement
> Components: Scheduler, Spark Core
> Reporter: Jeff Zhang
>
> Currently when speculation is enabled, other task attempts won't be killed if
> one task attempt in the same task is succeeded, it is not resource efficient,
> it would be better to kill other task attempts when one taskattempt belonging
> the same task is succeeded in speculation.
