Could not determine partitioner for tableId

Error message

Could not determine partitioner for tableId %s

What it means

In CassandraStreamHeader.serializer.deserialize, the SchemaLookup/table lookup for the deserialized tableId returns no partitioner, so the header cannot be completed: the receiving node lacks schema (or metadata) for the streamed table. Deserialization fails with 'Could not determine partitioner for tableId %s', aborting the stream message.

Solutions

1. Ensure the table metadata for the given tableId exists on this node before deserializing the stream header
2. Re-sync schema and restart the stream session
