Hi,
Most likely you have hit a bug. I've seen a couple of cases where node group
information in the show command provides the wrong output. Nodes will be
placed in node groups implicitly. If you have NoOfReplicas = 2 then the first
two nodes will be in node group 0, the next two in node group 1 and so forth.
So in your case they should all be in 0 unless you have set NoOfReplicas = 1
when node 3 should be in node group 1.
