Apache Spark reassigned SPARK-13343:
------------------------------------
Assignee: Apache Spark
> speculative tasks that didn't commit shouldn't be marked as success
> -------------------------------------------------------------------
>
> Key: SPARK-13343
> URL: https://issues.apache.org/jira/browse/SPARK-13343
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 1.6.0
> Reporter: Thomas Graves
> Assignee: Apache Spark
>
> Currently Speculative tasks that didn't commit can show up as success of
> failures (depending on timing of commit). This is a bit confusing because
> that task didn't really succeed in the sense it didn't write anything.
> I think these tasks should be marked as KILLED or something that is more
> obvious to the user exactly what happened. it is happened to hit the timing
> where it got a commit denied exception then it shows up as failed and counts
> against your task failures. It shouldn't count against task failures since
> that failure really doesn't matter.
> MapReduce handles these situation so perhaps we can look there for a model.
