ConnectionException while trying to connect with Astyanax over Java driver

[Ruchir Jha]

All,

I am trying to use the new astyanax over java driver to connect to
cassandra version 1.2.12,

Following settings are turned on in cassandra.yaml:

start_rpc: true
native_transport_port: 9042
start_native_transport: true

*Code to connect:*

final Supplier<List<Host>> hostSupplier = new Supplier<List<Host>>() {

            @Override
            public List<Host> get()
            {
                List<Host> hosts = new ArrayList<>();
                for(String hostPort :
StringUtil.getSetFromDelimitedString(seedHosts, ","))
                {
                    String[] pair = hostPort.split(":");
                    Host host = new Host(pair[0],
Integer.valueOf(pair[1]).intValue());
                    host.setRack("rack1");
                    hosts.add(host);
                }
                return hosts;
            }
        };

        // get keyspace
        AstyanaxContext<Keyspace> context = new AstyanaxContext.Builder()
                .forCluster(clusterName)
                .forKeyspace(keyspace)
                .withHostSupplier(hostSupplier)
                .withAstyanaxConfiguration(
                        new AstyanaxConfigurationImpl()

.setDiscoveryType(NodeDiscoveryType.DISCOVERY_SERVICE)

.setDiscoveryDelayInSeconds(60000).setCqlVersion("3.0.0").setTargetCassandraVersion("1.2.12")
                )
                .withConnectionPoolConfiguration(
                        new *JavaDriverConfigBuilder*().withPort(9042)
                                .build())
                .buildKeyspace(CqlFamilyFactory.getInstance());

        context.start();

*Exception in Cassandra Server logs:*

I also tried using the Java Driver 2.1.1, but I see the
NoHostAvailableException, and I feel the underlying reason is the same as
during connecting with astyanax java driver.
