Imran Rashid updated SPARK-10370:
---------------------------------
Component/s: (was: Spark Core)
Scheduler
> After a stages map outputs are registered, all running attempts should be
> marked as zombies
> -------------------------------------------------------------------------------------------
>
> Key: SPARK-10370
> URL: https://issues.apache.org/jira/browse/SPARK-10370
> Project: Spark
> Issue Type: Bug
> Components: Scheduler
> Affects Versions: 1.5.0
> Reporter: Imran Rashid
>
> Follow up to SPARK-5259. During stage retry, its possible for a stage to
> "complete" by registering all its map output and starting the downstream
> stages, before the latest task set has completed. This will result in the
> earlier task set continuing to submit tasks, that are both unnecessary and
> increase the chance of hitting SPARK-8029.
> Spark should mark all tasks sets for a stage as zombie as soon as its map
> output is registered. Note that this involves coordination between the
> various scheduler components ({{DAGScheduler}} and {{TaskSetManager}} at
> least) which isn't easily testable with the current setup.
> To be clear, this is *not* just referring to canceling running tasks (which
> may be taken care of by SPARK-2666). This is to make sure that the taskset
> is marked as a zombie, to prevent submitting *new* tasks from this task set.
