Target Version/s: (was: 2.1.1)
Fix Version/s: (was: 2.1.1)
> spark dynamic allocation should not idle timeout executors when tasks still
> to run
> ----------------------------------------------------------------------------------
>
> Key: SPARK-21656
> URL: https://issues.apache.org/jira/browse/SPARK-21656
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.1.1
> Reporter: Jong Yoon Lee
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> Right now spark lets go of executors when they are idle for the 60s (or
> configurable time). I have seen spark let them go when they are idle but they
> were really needed. I have seen this issue when the scheduler was waiting to
> get node locality but that takes longer then the default idle timeout. In
> these jobs the number of executors goes down really small (less than 10) but
> there are still like 80,000 tasks to run.
> We should consider not allowing executors to idle timeout if they are still
> needed according to the number of tasks to be run.
