> Project: Cassandra

> Reporter: Gary Dusbabek

> Fix For: 0.7.1

> 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.
