​After upgrading a schema, I'm getting lots of UnknownColumnFamilyException in the logs. However, all nodes have the same schema as reported by nodetool describecluster. I queried the system tables for the given column family UUID, but it doesn't appear in any of the schemas on any of the nodes. I restarted all clients, but that didn't help either.
The cluster was running 2.1.2 but I recently upgraded to 2.1.3. Any ideas? This is basically making our production cluster highly unresponsive. Tim
