Error while trying to connect cassandra database u

I'm working in a project which uses Spark streaming, Apache kafka and Cassandra. I use streaming-kafka integration. In kafka I have a producer which sends data using this configuration:

props.put("metadata.broker.list", KafkaProperties.ZOOKEEPER); props.put("bootstrap.servers", KafkaProperties.SERVER); props.put("client.id", "DemoProducer");

where ZOOKEEPER = localhost:2181, and SERVER = localhost:9092.

Once I send data I can receive it with spark, and I can consume it too. My spark configuration is:

SparkConf sparkConf = new SparkConf().setAppName("org.kakfa.spark.ConsumerData").setMaster("local[4]");
sparkConf.set("spark.cassandra.connection.host", "localhost");
JavaStreamingContext jssc = new JavaStreamingContext(sparkConf, new Duration(2000));

After that I am trying to store this data into cassandra database. But when I try to open session using this:

CassandraConnector connector = CassandraConnector.apply(jssc.sparkContext().getConf());
Session session = connector.openSession();

I get the following error:

Exception in thread "main" com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: localhost/127.0.0.1:9042 (com.datastax.driver.core.exceptions.InvalidQueryException: unconfigured table schema_keyspaces))

Regarding to cassandra, I'm using default configuration:

start_native_transport: true
native_transport_port: 9042
- seeds: "127.0.0.1"
cluster_name: 'Test Cluster'
rpc_address: localhost
rpc_port: 9160
start_rpc: true

I can manage to connect to cassandra from the command line using cqlsh localhost, getting the following message:

Connected to Test Cluster at 127.0.0.1:9042. [cqlsh 5.0.1 | Cassandra 3.0.5 | CQL spec 3.4.0 | Native protocol v4] Use HELP for help. cqlsh>

I used nodetool status too, which shows me this:

For running cassandra I invoke bin/cassandra -f

What I am trying to run is this:

try (Session session = connector.openSession()) {
        System.out.println("dentro del try");
        session.execute("DROP KEYSPACE IF EXISTS test");
        System.out.println("dentro del try - 1");
        session.execute("CREATE KEYSPACE test WITH replication = {'class': 'SimpleStrategy', 'replication_factor': 1}");
        System.out.println("dentro del try - 2");
        session.execute("CREATE TABLE test.users (id TEXT PRIMARY KEY, name TEXT)");
        System.out.println("dentro del try - 3");
    }

My pom.xml file looks like that:

I have no idea why I can't connect to cassandra using spark, is it configuration bad or what i am doing wrong?

Thank you!

com.datastax.driver.core.exceptions.InvalidQueryException: unconfigured table schema_keyspaces)

That error indicates an old driver with a new Cassandra version. Looking at the POM file, we find there the spark-cassandra-connector dependency declared twice. One uses version 1.6.0-m2 (GOOD) and the other 1.1.0-alpha2 (old).

Remove the references to the old dependencies 1.1.0-alpha2 from your config:

<dependency>
    <groupId>com.datastax.spark</groupId>
    <artifactId>spark-cassandra-connector_2.10</artifactId>
    <version>1.1.0-alpha2</version>
</dependency>
<dependency>
    <groupId>com.datastax.spark</groupId>
    <artifactId>spark-cassandra-connector-java_2.10</artifactId>
    <version>1.1.0-alpha2</version>
</dependency>
