Kafka consumer does not work from eclipse when kafka running inside VM

[shivam tiwari]

Kafka 0.8.2.2.3 and zookeper both are running inside VM. I was able to run
both producer and consumer within VM successfully using
kafka-console-producer.sh and kafka-console-consumer.sh respectively. Even
I was able to consume Kafka messages from host machine using
kafka-console-consumer.sh. But when I tried to run the consumer using java
from eclipse then zookeeper logs following error

Below is my Kafka consume code

package com.truckevent.producer;


import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Properties;

import kafka.consumer.Consumer;
import kafka.consumer.ConsumerConfig;
import kafka.consumer.ConsumerIterator;
import kafka.consumer.KafkaStream;
import kafka.javaapi.consumer.ConsumerConnector;


public class KafkaConsumer {

    public static void main(String[] args) throws Exception {

        String group = "hello" ;


        Properties props = new Properties();
        props.put("zookeeper.connect", "192.168.1.12:2181");
        props.put("group.id", group);
        props.put("zookeeper.session.timeout.ms", "20000");
        props.put("zookeeper.sync.time.ms", "2030");
        props.put("auto.commit.interval.ms", "10000");
        props.put("auto.offset.reset", "smallest");

        ConsumerConfig cf = new ConsumerConfig(props) ;

        ConsumerConnector consumer = Consumer.createJavaConsumerConnector(cf) ;

        String topic = "event" ;

        Map<String, Integer> topicCountMap = new HashMap<String, Integer>();
        topicCountMap.put(topic, new Integer(1));
        Map<String, List<KafkaStream<byte[], byte[]>>> consumerMap =
consumer.createMessageStreams(topicCountMap);
        List<KafkaStream<byte[], byte[]>> streams = consumerMap.get(topic);


        KafkaStream<byte[],byte[]> stream = streams.get(0) ;

        ConsumerIterator<byte[], byte[]> it = stream.iterator();
        int i = 1 ;
        while (it.hasNext()) {

            System.out.println(i + ": " + new String(it.next().message()));
            ++i;
        }
        consumer.shutdown();
    }
}


I am not sure why I am not able to consume messages from java code. Kafka
is running on port 6667 and zookeeper on 2181.
