Joshua McKenzie reassigned CASSANDRA-12236: ------------------------------------------- Assignee: Joshua McKenzie (was: Sylvain Lebresne) > 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 > Assignee: Joshua McKenzie > Fix For: 3.x > > Attachments: 12236.txt > > > 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)
