HI, Good morning. I am new to Kafka. So, please bear with me. I am using the new Producer and Consumer API with Kafka 0.9.0.1 running on Windows 7 laptop with zookeeper.
I was able to send messages using the new Producer API. I can see the messages in the Kafka data directory. However, when I run the consumer, it does not retrieve the messages. It keeps waiting for the messages indefinitely. My code (taken from Javadoc and modified) is as below: props.put("bootstrap.servers", "localhost:9092"); props.put("group.id", "new01"); props.put("enable.auto.commit", "true"); props.put("auto.commit.interval.ms", "1000"); props.put("session.timeout.ms", "30000"); props.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer"); props.put("value.deserializer", "org.apache.kafka.common.serialization.StringDeserializer"); KafkaConsumer<String, String> consumer = new KafkaConsumer<>(props); consumer.subscribe(Arrays.asList("new-producer")); while (true) { ConsumerRecords<String, String> records = consumer.poll(100); for (ConsumerRecord<String, String> record : records) System.out.printf("offset = %d, key = %s, value = %s", record.offset(), record.key(), record.value()); } Can anybody please tell me what went wrong?
