Subject [jira] [Updated] (CASSANDRA-12236) RTE from new CDC column breaks in flight queries.
Date Thu, 21 Jul 2016 16:04:20 GMT


Joshua McKenzie updated CASSANDRA-12236:
    Attachment: 12236.txt

We don't need to mess with null vs. empty set since cdc is a boolean on the table level with
the "v2" design and DC enabled/disabled is handled on the consumer level. It already defaults
to false in {{SchemaKeyspace.createTableParamsFromRow}} for backwards compatibility from older

Attaching a trivial patch to only add the param in {{SchemaKeyspace.addTableParamsToSchemaMutation}}
if cdc is enabled on the node.

> 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
>       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.
