Kafka Team,
I am using high level consumer API as shown below to read contents from the
topic.
Properties props = new Properties();
props.put("zookeeper.connect"
,"localhost:2181");
props.put" zookeeper.session.timeout.ms" ,"10000");
props.put("zookeeper.sync.time.ms" ,200);
props.put("auto.commit.interval.ms" ,"1000");
props.put("consumer.timeout.ms"
,"120000"
props.put("group.id"
,"TEST123");
ConsumerConfig config = new ConsumerConfig(props);
ConsumerConnector consumer = kafka.consumer.Consumer
.createJavaConsumerConnector(config);
Map<String, Integer> topicCountMap = new HashMap<String, Integer>();
topicCountMap.put("TEST", new Integer(1));
Map<String, List<KafkaStream<byte[], byte[]>>> consumerMap =
consumer.createMessageStreams(topicCountMap);
List<KafkaStream<byte[], byte[]>> streams = consumerMap.get("TEST");
// now launch all the threads
ThreadPoolExecutor executor = resource.getExecutor();
// now create an object to consume the messages
for (final KafkaStream<byte[], byte[]> stream : streams) {
TestTask task = new TestTask(stream);
executor.submit(task);
}
And the Testtask is just printing the messages.
The kafka logger shows the below statement
Consumer APP51_DFGHSFV1-1406836437053-9ed3b6a7 selected partitions : YYYY:0:
fetched offset = -1: consumed offset = -1,YYYY:1: fetched offset = -1: consumed
offset = -1
- [APP51_DFGHSFV1-1406836437053-9ed3b6a7],
Even when the fetched and consumed offset displays -1, I am not getting the
messages from the beginning
The retention window policy is set as -log.retention.hours=168
If I produce new messages, then those messages are consumed and I can see the
logged statements
If I use the simple consumer API and specify the starting offset as 0, then I
am able to read from the beginning
Are there any settings that would enable for new consumer group to read
messages from the beginning?
Thanks,
Srividhya
