[jira] [Created] (CASSANDRA-20343) Allow empty placements when deserializing cluster metadata

Marcus Eriksson created CASSANDRA-20343:
-------------------------------------------

             Summary: Allow empty placements when deserializing cluster metadata
                 Key: CASSANDRA-20343
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-20343
             Project: Apache Cassandra
          Issue Type: Bug
          Components: Transactional Cluster Metadata
            Reporter: Marcus Eriksson
            Assignee: Marcus Eriksson


On upgrade we might have a cluster with an old bad schema, for example containing NTS with references to datacenters that no longer exist - these replication strategies will not have any placements at all - handle that by allowing empty placements.
