> 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.
