[jira] [Commented] (CASSANDRA-15946) Communication problem between
C* 3 and C* 4 in in-jvm dtests
[ https://issues.apache.org/jira/browse/CASSANDRA-15946?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17157957#comment-17157957 ]
Jacek Lewandowski commented on CASSANDRA-15946:
-----------------------------------------------
Here is my patch for this: [https://github.com/apache/cassandra/pull/678]
Though, I'm not familiar with all of that testing infrastructure, so I'm waiting for comments if it should be fixed in a different way

> There is a communication problem when testing upgrades using in-JVM dtest between Cassandra 3 and 4.
> In a method {{registerInboundFilter}} of {{Instance}}, we get a message which was just received and we prepare it for filtering as part of which, we serialize the payload again. This is fine when dealing with incoming Cassandra 4 message, because we can serialize it. However when we get the Cassandra 3 message, which uses a different protocol, and we get something like {{REQUEST_RSP}}, we can surely deserialize it through some special deserialization path, but we cannot serialize the payload for it as there is no serializer defined for {{REQUEST_RSP}} - no wonder, why would Cassandra 4.0 need to be able to serialize Cassandra 3.0 payloads?
