             Summary: insert if not exists, with replication factor of 2 
doesn't work
                 Key: CASSANDRA-14584
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14584
             Project: Cassandra
          Issue Type: Bug
            Reporter: arik


Running with a single node cluster.

My keyspace has a replication factor of 2.

Insert if not exists doesn't work on that setup.

Produce the following error:
