A Simple scenario, Help needed

[Prasanna Rajaperumal]

Hi All,

I am trying out a very simple scenario and I dont seem to get it working. It 
would be great if I am pointed to some things here.

I have set up a 2 node cluster, cassandra.yaml being the default and same for 
each other than the seed: being each other and I have set the Thrift RPC 
address and listen_address to publicly available hostnames. Replication factory 
is set to 1

I have a client (using Hector) to do some basic operations like write, read, 
delete.

        CassandraHostConfigurator config = new 
CassandraHostConfigurator("arti-dev-logger-2:9160,arti-dev-logger-1:9160");
        config.setAutoDiscoverHosts(true);
        Cluster cluster = HFactory.createCluster("dev_cluster", config);
        Keyspace artiKeyspace = 
HFactory.createKeyspace(this.getArti_persistence_cassandra_keyspace(), cluster, 
new ConsistencyLevelPolicy(){
                        @Override
                        public HConsistencyLevel get(OperationType op) {
                                return HConsistencyLevel.ONE;
                        }
                        @Override
                        public HConsistencyLevel get(OperationType op, String 
cfName) {
                                return HConsistencyLevel.ONE;
                        }
        });

Nodetool show the ring fine.

I observe, If I have arti-dev-logger-1 down and run my test against against the 
cluster, my test is successful.
If I bring up the arti-dev-logger-1 and take down arti-dev-logger-2, My test 
complains 

com.cisco.step.arti.persistence.CassandraException: : May not be enough 
replicas present to handle consistency level.

I would imagine I am doing something very fundamental here, I have not attached 
any test case hoping that any experienced person looking at might be able to 
figure out what is going on right away.

Thanks
