-------------------------------------------
Summary: Subscribe Earliest is not working as in 0.10.2.1
Key: KAFKA-5537
URL: https://issues.apache.org/jira/browse/KAFKA-5537
Project: Kafka
Issue Type: Bug
Affects Versions: 0.11.0.0
Reporter: Michael Andre Pearce
Priority: Critical
We have seen issue with subscription where auto offset when set to earliest
does not behave the same as in 0.10.2.1 release.
We have managed to create a repeatable test for this, which passes when
pointing to 0.10.2.1 broker.
@Test
public void testSubscribeEarliest(){
Properties properties = new Properties();
properties.setProperty(CommonClientConfigs.BOOTSTRAP_SERVERS_CONFIG,
bootstrap);
properties.setProperty(ConsumerConfig.GROUP_ID_CONFIG, "test-group");
properties.setProperty(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG,
"earliest");
KafkaProducer<byte[], byte[]> kafkaProducer = new
KafkaProducer<>(properties, new ByteArraySerializer(), new
ByteArraySerializer());
kafkaProducer.send(new ProducerRecord<>("topic", "hello".getBytes()));
KafkaConsumer<byte[], byte[]> kafkaConsumer =
new KafkaConsumer<>(properties, new ByteArrayDeserializer(), new
ByteArrayDeserializer());
kafkaConsumer.subscribe(Collections.singletonList("topic"));
ConsumerRecords<byte[], byte[]> consumerRecords =
kafkaConsumer.poll(1000);
assertEquals(1, consumerRecords.count());
}
