Hello, everyone!
I will share with you how to deal with the problem of consuming failure using port 21005 when using Kafka
Context and Symptom
Port 21005 could be used for consumption normally, and a user had the kafkaadmin permission. A topic was assigned with the ACL permission. However, an error was reported when port 21007 was used to generate consumption.
Checked the kafka-root log and found a large number of reported errors.
Ran systemctl status sssd and found the process was abnormal.
Cause Analysis
The sssd process was abnormal. As a result, the consumer group failed to be obtained and the consumption production was abnormal.
Solution
For details, see section about how to handle sssd exceptions in the product documentation.
