Description

Currently, nodes with one layer topology are allowed to join in the cluster that with enabling NodeGroup layer which cause some exception cases.
When NodeGroup layer is enabled, the cluster should assumes that at least two layer (Rack/NodeGroup) is valid topology for each nodes, so should throw exceptions for one layer node in joining.
