TiCDC encountered an error when starting a task to send to Kafka. The error is as follows. Can someone take a look?
Is it deployed on an external network?
Can you show the CDC configuration file?
There might be an issue with your Kafka configuration. Check the advertised.listeners setting.
Which configuration file? If it’s changefeed, only these are configured.
listeners=PLAINTEXT://192.168.206.191:9092
advertised.listeners=PLAINTEXT://bigdata001.bdmstest.com:9092
So where did you get this 103 external network address from? Configured in the hosts file?
It’s quite confusing. CDC and Kafka are supposed to be under the same gateway, and the ports are all open. I don’t know how this external network address came up.
Try using telnet to check if the port 9092 on 192.168.206.191 is accessible.
So, is that external IP address 103.224.182.210 the address of your WIFI? Are both the wireless network card and the wired network card enabled at the same time?
After changing the Kafka version, there were no more issues.
TiCDC version: 5.0.4. Changing the Kafka version from 2.12-2.6.3 to 2.11-2.0.1 resolved the problem.
Haha! You can organize it and write an article, a guide to avoiding pitfalls.
Then it should be a compatibility issue~
I guess the new version of Kafka is only compatible with the new version of TiDB.
Yes, that’s correct. Another question, is the official documentation no longer maintained for versions below 6.5?
