Jonathan Ellis commented on CASSANDRA-1970:
-------------------------------------------
Sure, but it still seems like it is easier to say "The first gossip message
will always follow this format" and keep that in legacy mode if necessary, than
to add this extra layer.

> URL: https://issues.apache.org/jira/browse/CASSANDRA-1970
> Project: Cassandra
> Issue Type: Sub-task
> Reporter: Gary Dusbabek

> Priority: Minor
> 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.
