Kafka Producer Send String Not Working - apache-kafka

Question

I am trying to make a kafka producer that sends a string "This program is running" to a kafka topic. I am not sure why it is not working. Below is the following code. I am not Cloudera distribution.
package kafka_test;
import java.util.Properties;
import org.apache.kafka.clients.producer.KafkaProducer;
import org.apache.kafka.clients.producer.ProducerConfig;
import org.apache.kafka.clients.producer.ProducerRecord;
import org.apache.kafka.common.serialization.StringSerializer;
public class DataMovement {
public static void main(String[] args) {
String kafkaTopic = args[0];
Properties props = new Properties();
props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, "server:9092");
props.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, StringSerializer.class.getName());
props.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class.getName());
KafkaProducer<String, String> producer = new KafkaProducer<String, String>(props);
ProducerRecord<String, String> producerRecord = new ProducerRecord<String, String>(kafkaTopic, null, "This program is running.");
producer.send(producerRecord);
producer.close();
}
}
I don't get an error message but a timeout:
It also outputs lots of information about the Kafka, ssl, passowrd, client.id etc.
16/10/31 10:25:46 INFO utils.AppInfoParser: Kafka version : 0.9.0.1
16/10/31 10:25:46 INFO utils.AppInfoParser: Kafka commitId : commitid
16/10/31 10:26:46 INFO producer.KafkaProducer: Closing the Kafka producer with timeoutMillis = 9223372036854775807 ms.

The code works fine. Problem was the server:9092 should be the address of the designated broker of the Kafka cluster (I had it targeted on the active broker, they are different).
