when i ran spark submit on k8s master the driver pod is stuck in Waiting: PodInitializing state.
I tried kubectl describe node on the node where trhe driver pod is running this is what i got ,i do see there is overcommit on resources but i expected kubernetes scheduler not to schedule if resources in node are overcommitted or node is in Not Ready state ,in this case node is in Ready State but i observe same behaviour if node is in "Not Ready" state
