> Speculation kill causing finished stage recomputed
> --------------------------------------------------
>
> Key: SPARK-26612
> URL: https://issues.apache.org/jira/browse/SPARK-26612
> Project: Spark
> Issue Type: Bug
> Components: Scheduler, Spark Core
> Affects Versions: 2.1.0
> Reporter: liupengcheng
> Priority: Major
>
> In our production spark cluster, we encoutered this issue.
> A more detailed explaination:
> Let's say we have two stage: stage0.0 and stage1.0, and stage 0 is a shuffleMapStage, and stage1 has dependency on stage0, and we enabled spark.speculation.
> when task0.0 of stage1.0 finished, and is trying to kill task0.1(speculative) of stage1.0, task0.1 throws a wrapped FetchFailedException whose root cause is java.nio.channels.ClosedByInterruptException(caused by speculation kill).
