Cassandra-Java-Driver and C* v3.* -- failed to connect
Hi All,
I'm 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 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.

Yes, I've tried 3.0.0-rc1. It can not connect to the cluster v3.1.1

Serj, there have been an RC recently which should give you a stable API and
the latest bug fixes:

I've just tried cassandra-driver-core v3.0.0-alpha5 and it works with C*
3.1.1. At least it connects to the cluster.

Hi Serj,
Have you tried the 3.0 rc? Due to some changes in the system tables, the
older versions of the driver do have problems connecting.
