Jonathan Ellis commented on CASSANDRA-2818:
-------------------------------------------
Not sure what's going on. Here's what's supposed to happen:
If new node N is contacted first by old node M, N records the version of M and
generates messages at that version. M never knows that N is actually newer.
If M is contacted first, we expect to see the above message a few times, but M
adds N to its gossip list after the first time. Once N gets a gossip from M, it
will know to use M's version when creating messages.
I don't see anything obviously wrong with this code. :(
> A 0.8.1 version node can't join the ring made up of 0.8.0 nodes.
