        String serverIp = "127.0.0.1";
        String keyspace = "ranga";
        CassandraConnection connection;

        Cluster cluster = Cluster.builder().addContactPoints(serverIp).build();

        Session session = cluster.connect(keyspace);

        String cqlStatement = "SELECT * FROM employee";
        for (Row row : session.execute(cqlStatement)) {
            System.out.println(row.toString());
        }

    }

}

So and getting Exception Exception in thread "main" com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: /127.0.0.1:9042 (com.datastax.driver.core.exceptions.InvalidQueryException: unconfigure
