> Key: SPARK-11163
> URL: https://issues.apache.org/jira/browse/SPARK-11163
> Project: Spark
> Issue Type: Improvement
> Components: Scheduler
> Reporter: Kay Ousterhout
> Assignee: Kay Ousterhout
> Priority: Minor
>
> The proposed commit removes unnecessary calls to addPendingTask in
> TaskSetManager.executorLost. These calls are unnecessary: for
> tasks that are still pending and haven't been launched, they're
> still in all of the correct pending lists, so calling addPendingTask
> has no effect. For tasks that are currently running (which may still be
> in the pending lists, depending on how they were scheduled), we call
> addPendingTask in handleFailedTask, so the calls at the beginning
> of executorLost are redundant.
> I think these calls are left over from when we re-computed the locality
> levels in addPendingTask; now that we call recomputeLocality separately,
> I don't think these are necessary.
