As far as I recall, the first message is needed to announce that there =
is a new node that wishes to join the cluster. The node will receive an =
order number and will take its place in the cluster ring after the =
message is processed.

The second message is need to finalize the join process: change a =
topology version, send and process NODE_JOIN events, etc.
