Internal Messaging should be backwards compatible
-------------------------------------------------
Key: CASSANDRA-1015
URL: https://issues.apache.org/jira/browse/CASSANDRA-1015
Project: Cassandra
Issue Type: Bug
Affects Versions: 0.6, 0.6.1, 0.6.2, 0.7, 0.8
Reporter: Ryan King
Currently, incompatible changes in the node-to-node communication prevent
rolling restarts of clusters.
In order to fix this we should:
1) use a framework that makes doing compatible changes easy
2) have a policy of only making compatible changes between versions n and n+1*
* Running multiple versions should only be supported for small periods of time.
Running clusters of mixed version is not needed here.
