khogeland edited a comment on issue #26687: [SPARK-30055][k8s] Allow configuration of restart policy for Kubernetes pods URL: https://github.com/apache/spark/pull/26687#issuecomment-561743930 >Now, let's assume we restart the executors I think you're misunderstanding what the restart policy does. The restart policy is a Kubernetes setting that controls what the host does when the pod containers exit (in this case, when the executor process exits). Setting the restart policy to always tells the host to always restart _executors processes that have exited._ It is a failure handling mechanism. >in what scenario "always" restarting the executors are better than the driver resending tasks? These are orthogonal and there is no trade-off. The driver resends tasks to available executors. Kubernetes keeps the executors running.
