URL: https://github.com/apache/rocketmq/issues/6178
** QUESTION**
1. Please describe the issue you observed:
- What did you do (The steps to reproduce)?
My requirement is to pull messages from MQ regularly.
- What is expected to see?
I hope to see that the message can be pulled by me normally
- What did you see instead?
The strange thing is that I used the subscription mode when I officially
pulled the news, but I couldn't pull the news, and all I pulled were empty
collections. There is no problem using push mode. Here is the consumer class
(org.apache.rocketmq.example.simple.LitePullConsumerSubscribe) from the source
code that I am using. Hope to get your reply.
2. Please tell us about your environment:
Version is 4.4.0，The symptoms of the stand-alone cluster are the same
4. Other information (e.g. detailed explanation, logs, related issues,
suggestions on how to fix, etc):
` class LitePullConsumerSubscribe {
public static volatile boolean running = true;
public static void main(String[] args) throws Exception {
DefaultLitePullConsumer litePullConsumer = new
DefaultLitePullConsumer("test-consumer");
litePullConsumer.setConsumeFromWhere(ConsumeFromWhere.CONSUME_FROM_FIRST_OFFSET);
litePullConsumer.setNamesrvAddr("11.112.222.124:9876");
litePullConsumer.subscribe("yyds", "*");
litePullConsumer.start();
try {
while (running) {
List<MessageExt> messageExts = litePullConsumer.poll();
System.out.printf("%s%n", messageExts);
}
} finally {
litePullConsumer.shutdown();
}
}
}`
