> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 1.6.0
> Reporter: Jimmy Xiang
> Priority: Minor
>
> With dynamic executor allocation enabled on yarn mode, after one job is
> finished for a while, submit another job, then there is race between killing
> idle executors and scheduling new task on these executors. Sometimes, some
> executor is killed right after a task is scheduled on it.
