Target Version:
In the core scheduler the nodes are added when the shim tells it to add a new node. If the node is made unschedulable (cordon node) that state is passed on and the core is updated (apache/incubator-yunikorn-core#57)
The core can also decommission a node however the shim currently does not support sending a decommission to the core. That needs to be added based on the state of the cluster and the nodes on the k8s side:
