Brandon Williams updated CASSANDRA-2818:
----------------------------------------
Attachment: 2818-v3.txt
v2 has two problems:
* It shuts the connection down slightly too aggressively, causing an exception
on the remote side before setVersion gets called.
* It stores the remote's version even when it is greater, causing the lower
version node to always report itself as the newer version to the newer node.
v3 address the first problem by sleeping for a half second before closing, and
addresses the second by only calling setVersion if the remote side is
compatible, otherwise it calls addSavedEndpoint before disconnecting so that it
will reconnect.
> 0.8.0 is unable to participate with nodes using a _newer_ protocol version

> When a 0.8.1 node tries to join a 0.8.0 ring, we see an endless supply of
> these in system.log:

> Received connection from newer protocol version. Ignorning message.
