Trying to connect to C* v3.1.1 cluster.
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

// 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.

I've just tried to use cassandra-driver-core-3.0.0_rc1 and
cassandra-driver-core-3.0.0_beta1 with C* 2.2.4
(cassandra-all-2.2.4). And neither of them can connect to the
local cluster. But cassandra-driver-core-2.1.9. Am I doing wrong?
Happy New Year!

Not yet. The latestest DSE (4.8.3) is shipped with a patched
version of Cassandra 2.11.
You can find this information on their website.
4.8 Release note :
https://docs.datastax.com/en/datastax_enterprise/4.8/datastax_enterprise/RNdse.html
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.
