> Components: Scheduler, Spark Core
> Affects Versions: 2.4.0
> Reporter: Qingxin Wu
> Assignee: Apache Spark
> Priority: Major
>
> I enable dynamic allocation feature with *spark-shell* and do not submit any
> task. After *spark.dynamicAllocation.executorIdleTimeout* seconds(default
> 60s), there is still one active executor, which is abnormal. All idle
> executors are timeout and should be removed.(default
> *spark.dynamicAllocation.minExecutors*=0). The spark-shell command show below:
> {code:java}
> spark-shell --master=yarn --conf spark.ui.port=8040 --conf
> spark.dynamicAllocation.enabled=true --conf
> spark.dynamicAllocation.maxExecutors=8 --conf
> spark.dynamicAllocation.initialExecutors=4 --conf
> spark.shuffle.service.enabled=true
> {code}
