Jeremiah Jordan created CASSANDRA-12236: -------------------------------------------
Summary: RTE from new CDC column breaks in flight queries. Key: CASSANDRA-12236 URL: https://issues.apache.org/jira/browse/CASSANDRA-12236 Project: Cassandra Issue Type: Bug Reporter: Jeremiah Jordan Priority: Blocker 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. {noformat} - 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. {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
