I am facing some unexpected issues.
Here you go the detailed information
RF=2 Cluster size=3 Write Consistency= Quorum
Few configurations cassandra.yaml
endpoint_snitch: GossipingPropertyFileSnitch
Keyspace Infirmation
describe keyspace test;
CREATE KEYSPACE test WITH replication = {'class': 'SimpleStrategy', 'replication_factor': '2'} AND durable_writes = true;
Test Case
1) I keep the one node down from the 3 node cluster. 2 Node is up but
Getting below Error

As per the log, one node is live so data should be inserted at least in one node and acknowledgement should be received from one node of writing data to DSE. I am surprised why data did not insert into any one live node of the cluster. As I explained above one node is down among the 3 node cluster.
