     [ https://issues.apache.org/jira/browse/CASSANDRA-12236?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sylvain Lebresne updated CASSANDRA-12236:
-----------------------------------------
    Status: Patch Available  (was: Open)

Btw, I haven't run the upgrade tests at all, so I haven't verified this fixes the upgrade problem. If someone could trigger those (once maybe the utest and dtests shows the patch isn't too broken), that would be great.

> This RTE is not harmless. It will cause the internode connection to break which will cause all in flight requests between these nodes to die/timeout.

>     - Due to changes in schema migration handling and the storage format after 3.0, you will
>       see error messages such as:
>          "java.lang.RuntimeException: Unknown column cdc during deserialization"
>       in your system logs on a mixed-version cluster during upgrades. This error message
>       is harmless and due to the 3.8 nodes having cdc added to their schema tables while
>       the <3.8 nodes do not. This message should cease once all nodes are upgraded to 3.8.
>       As always, refrain from schema changes during cluster upgrades.
