> Key: SPARK-13965
> URL: https://issues.apache.org/jira/browse/SPARK-13965
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.6.1
> Reporter: Devaraj K
>
> When we enable speculation, Driver would launch additional attempts for the
> same task if it founds that attempt is progressing slow compared to other
> tasks average progress and then there will be multiple task attempts in
> running state.
> At present, if any one attempt gets succeeded others would be keep running
> (even they could run till the job completion) and cannot be given these slots
> to other tasks in same stage or in next stages.
> We can kill these running task attempts when any other attempt gets succeeded
> and can be given the slots to run other tasks.
