> Key: SPARK-19596
> URL: https://issues.apache.org/jira/browse/SPARK-19596
> Project: Spark
> Issue Type: Improvement
> Components: Scheduler
> Affects Versions: 2.2.0
> Reporter: Imran Rashid
>
> Fetch Failures can lead to multiple simultaneous tasksets for one stage. The stage may
eventually be finished by task completions from a prior stage attempt. When this happens,
the most recent taskset is not marked as a zombie. This means that taskset may continue to
submit new tasks even after the stage is complete.
> This is not a correctness issue, but it will effect performance, as cluster resources
will get tied up running tasks that are not needed.
> This is a follow up to https://issues.apache.org/jira/browse/SPARK-19565. See some discussion
in the pr for that issue: https://github.com/apache/spark/pull/16901
