[jira] [Created] (CASSANDRA-15501) Duplicate results with DISTINCT queries in mixed mode 2.1/3.0

Marcus Eriksson created CASSANDRA-15501:

             Summary: Duplicate results with DISTINCT queries in mixed mode 2.1/3.0
                 Key: CASSANDRA-15501
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-15501
             Project: Cassandra
          Issue Type: Bug
            Reporter: Marcus Eriksson
            Assignee: Marcus Eriksson


When a client switches coordinator from a 2.1 node to a 3.0 node it sends a 2.1 paging state to the 3.0 node. The 2.1 {{PagingState}} does not have {{remainingInPartition}} so on the 3.0 side we default this to Integer.MAX_VALUE. This value is then used to decide if the lastKey should be included in the result.
