[jira] [Created] (CASSANDRA-20489) Avoid failing queries when epoch changes and replica goes up/down

Marcus Eriksson created CASSANDRA-20489:
-------------------------------------------

             Summary: Avoid failing queries when epoch changes and replica goes up/down
                 Key: CASSANDRA-20489
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-20489
             Project: Apache Cassandra
          Issue Type: Bug
          Components: Transactional Cluster Metadata
            Reporter: Marcus Eriksson
            Assignee: Marcus Eriksson


To make sure that we got responses from the correct replicas we recompute the replica plan for queries if the epoch changes during the query to make sure we got responses from a quorum of the nodes in the recomputed replica plan. 

Problem is that this recomputation is filtering away down nodes, so we can fail queries if the coordinator marks a replica down during the query and the epoch changes, even though the placements have not changed.
