各位大神 这段话翻译是什么意思,container被抢是,这个任务可以在其他executor更好的执行,然后把资源让出来?

// Preemption is not the fault of the running tasks, since YARN preempts containers
            // merely to do resource sharing, and tasks that fail due to preempted executors could
            // just as easily finish on any other executor. See SPARK-8167.
            (false, s"Container ${containerId}${onHostStr} was preempted.")
