-----------------------------------

             Summary: Integration test with embedded kafka.
                 Key: KAFKA-6339
                 URL: https://issues.apache.org/jira/browse/KAFKA-6339
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 0.11.0.2
            Reporter: DHRUV BANSAL


I am using Kafka version - 0.11.0.2

Trying to write an integration test for one of the components I am writing over Kafka.
Following code works fine with Kafka version 0.10.0.0 but not working with mentioned version (0.11.0.2)
{{
// setup Zookeeper
		EmbeddedZookeeper embeddedZookeeper = new EmbeddedZookeeper();
		String zkConnect = ZKHOST + ":" + embeddedZookeeper.port();
		ZkClient zkClient = new ZkClient(zkConnect, 30000, 30000, ZKStringSerializer$.MODULE$);
		ZkUtils zkUtils = ZkUtils.apply(zkClient, false);

		// setup Broker
		Properties brokerProps = new Properties();
		brokerProps.setProperty("zookeeper.connect", zkConnect);
		brokerProps.setProperty("broker.id", "0");
		brokerProps.setProperty("offsets.topic.replication.factor", "1");
		String kafka_log_path = Files.createTempDirectory("kafka-").toAbsolutePath().toString();
		System.out.println("kafka log path " + kafka_log_path);
		brokerProps.setProperty("log.dirs", kafka_log_path);
		brokerProps.setProperty("listeners", "PLAINTEXT://" + BROKERHOST + ":" + BROKERPORT);
		KafkaConfig config = new KafkaConfig(brokerProps);
		Time mock = new MockTime();
		KafkaServer kafkaServer = TestUtils.createServer(config, mock);

		// create topic
		AdminUtils.createTopic(zkUtils, TOPIC, 1, 1, new Properties(), RackAwareMode.Disabled$.MODULE$);

		// setup producer
		Properties producerProps = new Properties();
		producerProps.setProperty("bootstrap.servers", BROKERHOST + ":" + BROKERPORT);
		producerProps.setProperty("key.serializer", "org.apache.kafka.common.serialization.IntegerSerializer");
		producerProps.setProperty("value.serializer", "org.apache.kafka.common.serialization.ByteArraySerializer");
		KafkaProducer<Integer, byte[]> producer = new KafkaProducer<Integer, byte[]>(producerProps);

		// setup consumer
		Properties consumerProps = new Properties();
		consumerProps.setProperty("bootstrap.servers", BROKERHOST + ":" + BROKERPORT);
		consumerProps.setProperty("group.id", "group0");
		consumerProps.setProperty("client.id", "consumer0");
		consumerProps.setProperty("key.deserializer", "org.apache.kafka.common.serialization.IntegerDeserializer");
		consumerProps.setProperty("value.deserializer", "org.apache.kafka.common.serialization.ByteArrayDeserializer");
		consumerProps.put("auto.offset.reset", "earliest"); // to make sure the consumer starts from the beginning of
															// the topic

		KafkaConsumer<Integer, byte[]> consumer = new KafkaConsumer<>(consumerProps);
		consumer.subscribe(Arrays.asList(TOPIC));

		// send message
		ProducerRecord<Integer, byte[]> data = new ProducerRecord<>(TOPIC, 42,
				"test-message".getBytes(StandardCharsets.UTF_8));
		Future<RecordMetadata> record = producer.send(data);
		RecordMetadata metadata = record.get();

		// starting consumer
		ConsumerRecords<Integer, byte[]> records = consumer.poll(3000);
		assertEquals(1, records.count());
		Iterator<ConsumerRecord<Integer, byte[]>> recordIterator = records.iterator();
		ConsumerRecord<Integer, byte[]> consumedRecord = recordIterator.next();
		System.out.printf("offset = %d, key = %s, value = %s", consumedRecord.offset(), consumedRecord.key(),
				consumedRecord.value());
		assertEquals(42, (int) consumedRecord.key());
		assertEquals("test-message", new String(consumedRecord.value(), StandardCharsets.UTF_8));

		kafkaServer.shutdown();
		zkClient.close();
		embeddedZookeeper.shutdown();
}}

Please provide support for the same and there should be proper documentation for the intergration test with each release.
