Jason Gustafson created KAFKA-10239:
---------------------------------------
Summary: The groupInstanceId field in DescribeGroup response
should be ignorable
Key: KAFKA-10239
URL: https://issues.apache.org/jira/browse/KAFKA-10239
Project: Kafka
Issue Type: Bug
Reporter: Jason Gustafson
Fix For: 2.6.0
We noticed the following error in the logs in the handling of a DescribeGroup
request:
```
org.apache.kafka.common.errors.UnsupportedVersionException: Attempted to write
a non-default groupInstanceId at version 3
```
The problem is that the field is not marked as ignorable. So if the user is
relying on static membership and uses an older AdminClient, they will see this
error.
