HScarb opened a new issue, #5844:
URL: https://github.com/apache/rocketmq/issues/5844
1. Please describe the issue you observed:
- What did you do (The steps to reproduce)?
1. Use pop consume API `MQClientAPIImpl.popMessageAsync` to pop a message
from topic
2. Use MQAdmin consumerProgress/consumerStatus/consumerConnection command
to examine pop consumer stats
- What is expected to see?
Consumer stats returns properly
- What did you see instead?
```log
MQClientException: CODE: 17 DESC: No topic route info in name server for
the topic: %RETRY%cid-test
```
2. Please tell us about your environment:
Rocketmq 5.0.1-snapshot, latest develop branch
3. Other information (e.g. detailed explanation, logs, related issues,
suggestions on how to fix, etc):
`consumerProgress/consumerStatus/consumerConnection`
These three commands both build and examine route info for normal retry
topic of pop consumer, that's where the exception raises, as pop consumer won't
create a normal retry topic.
---
I didn't come up with a perfect solution for this issue, but I have several
approches
1. Build a dummy retry topic when a consumer call pop API for the first
time.
2. Catch the exception raised by `examineTopicRouteInfo`, so the MQAdmin
commands would execute without exception
