> Although the plugin selects a certain node, the default scheduler may not
> schedule the pod on the plugin-selected node. In the below example, Yunikorn
> selected node host-05.shared-ek8s-dev-01.kcloud.cloudera.com. However, the
> pod was scheduled on host-01.shared-ek8s-dev-01.kcloud.cloudera.com.
> Internally, Yunikorn still incorrectly believes that the node was scheduled
> on host-05.shared-ek8s-dev-01.kcloud.cloudera.com.
