It works nice with cqlsh

$ cqlsh
Connected to Test Cluster at 127.0.0.1:9042.
[cqlsh 5.0.1 | Cassandra 3.1.1 | CQL spec 3.3.1 | Native protocol v4]

But doesn't work with cassandra-driver-core.
I use next mvn deps:

<dependency>
    <groupId>com.datastax.cassandra</groupId>
    <artifactId>cassandra-driver-core</artifactId>
    <version>3.0.0-rc1</version>
</dependency>

<dependency>
    <groupId>org.apache.cassandra</groupId>
    <artifactId>cassandra-all</artifactId>
    <version>3.1.1</version>
</dependency>

And connect in the next code:

Cluster.Builder builder = Cluster.builder()
        .withProtocolVersion(ProtocolVersion.V4)
        .withPort(9042)
        .addContactPoint("127.0.0.1");

cluster = builder.build();
Metadata metadata = cluster.getMetadata();

And it doesn't work. I get the exception:
com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: /127.0.0.1:9042 (com.datastax.driver.core.exceptions.TransportException: [/127.0.0.1] Cannot connect))

    at com.datastax.driver.core.Cluster$Manager.init(Cluster.java:1382)
    at com.datastax.driver.core.Cluster.getMetadata(Cluster.java:393)

Everything is ok for C* 2.2.4 when I use

$ cqlsh
Connected to Test Cluster at 127.0.0.1:9042.
[cqlsh 5.0.1 | Cassandra 2.2.4 | CQL spec 3.3.1 | Native protocol v4]

</dependency>

<dependency>
    <groupId>org.apache.cassandra</groupId>
    <artifactId>cassandra-all</artifactId>
    <version>3.1.1</version>
</dependency>

Cluster.Builder builder = Cluster.builder()
        .withPort(9042)
        .addContactPoint("127.0.0.1");

You can find this information on their website. 

From this page in the menu you can navigate and unroll the menu Product Guide > Datastax Enterprise it should contain DSE versions.

And there's always other sources like the blog.

Cassandra 3.x should be shipped with DSE 5.x early next year.
