Description

Blocklist unblockResources does not update the existing pending resource request from YARN/K8S. It updates only for the new resource requests. The existing pending resource requests are not scheduled on the nodes which are unblocked.

ResourceManager#unblockResources has to notify YarnResourceManagerDriver/KubernetesResourceManagerDriver so that the driver updates the pending resource request. YarnResourceManagerDriver#tryUpdateApplicationBlockList could be called during unblockResources.
