zubchenok opened a new issue #1455: MessageID has always batch index 0 when sending messages in a batch
URL: https://github.com/apache/incubator-pulsar/issues/1455
 
 
   When I send messages I always get 0 in batchIndex component of MessageID. Here is a unit test that reproduce the issue:
   `    @Test
       public void testSameBatchIndex() throws Exception
       {
           String topicName = "persistent://test-prop/vv/ns1/test-" + UUID.randomUUID();
           PulsarClient pulsarClient = PulsarClient.create("pulsar://vv:6650");
   
           Producer producer = pulsarClient.createProducer(topicName, new ProducerConfiguration()
                   .setBatchingEnabled(true)
                   .setBatchingMaxMessages(1000)
                   .setBatchingMaxPublishDelay(1, TimeUnit.SECONDS)
           );
   
           Consumer consumer = pulsarClient.subscribe(topicName, "subscription", new ConsumerConfiguration()
                   .setMessageListener((consumer1, message) -> System.out.println("Read: " + message.getMessageId()))
           );
   
           producer.sendAsync("A".getBytes()).whenCompleteAsync((messageId, throwable) -> {
               System.out.println("A: " + messageId);
           });
           producer.sendAsync("B".getBytes()).whenCompleteAsync((messageId, throwable) -> {
               System.out.println("B: " + messageId);
           });
           producer.sendAsync("C".getBytes()).whenCompleteAsync((messageId, throwable) -> {
               System.out.println("C: " + messageId);
           });
   
           Thread.sleep(3333);
   
           consumer.close();
           producer.close();
           pulsarClient.close();
       }
   `
   
   Output is 
   `
   A: 1286:0:-1:0
   B: 1286:0:-1:0
   C: 1286:0:-1:0
   Read: 1286:0:-1:0
   Read: 1286:0:-1:1
   Read: 1286:0:-1:2
   `
   
   Expected output is
   `
   A: 1286:0:-1:0
   B: 1286:0:-1:1
   C: 1286:0:-1:2
   Read: 1286:0:-1:0
   Read: 1286:0:-1:1
   Read: 1286:0:-1:2
   `
