Gary Dusbabek commented on CASSANDRA-1970:
------------------------------------------
I don't think relying on gossip is reliable enough. For instance, consider a N
node joining a cluster of N-1 nodes. The first message sent will be a gossip
message that likely won't be understood.

> Project: Cassandra

> Fix For: 0.8

>
> When a new new node (version N) contacts an old node (version N-1) for the
> first time, the old node will not understand the message. One resolution
> mechanism would be for the old node to "bounce" the message back to the
> sender. The sender would then respond by translating the message to the
> appropriate version and resending it.
> For this to work, 0.7.1 will need to have the "bounce" feature.
