T Jake Luciani updated CASSANDRA-15703:
---------------------------------------
Fix Version/s: 3.11.x
> When CDC is disabled bootstrapping breaks
> -----------------------------------------
>
> Key: CASSANDRA-15703
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15703
> Project: Cassandra
> Issue Type: Bug
> Components: Consistency/Bootstrap and Decommission
> Reporter: T Jake Luciani
> Priority: Normal
> Fix For: 3.11.x
>
>
> Related to CASSANDRA-12697
> There is an edge case left over. If a cluster had enabled CDC on a table
> then subsequently set cdc=false, subsequent bootstraps break.
>
> This is because the cdc column is false on the existing nodes but null on the
> bootstrapping node, causing the schema sha to never match.
>
> There are a couple possible fixes:
> 1. Since 12697 was only about upgrades we can serialize the cdc column IFF
> the cluster nodes are all on the same version.
> 2. We can force cdc=false on all tables where it's null.
>
> I think #1 is probably simpler. #2 would probably cause more of the same
> problem if nodes are not all updated with the fix.
