------------------------------------
Hello [~rjoerger]
# this issue is enough to track the problem so another issue is unnecessary
# We are not intend to include default `segment.bytes` in the output but it
was printed(due to an bug), but this bug has been around for a long time so
[~mimaison] suggest we keep this bug in the future(make it bug-compatible)
# Since we are trying to keep its unchanged, so KIP is unnecessary
# This is the source of the bug, currently we haven't find it, you can
investigate it and add a comment to it to explain why we should keep this bug.
> kafka-topics describe topic with default config will show `segment.bytes`
> overridden config

> Key: KAFKA-13718
> URL: https://issues.apache.org/jira/browse/KAFKA-13718
> Project: Kafka
> Issue Type: Bug
> Components: tools
> Affects Versions: 3.1.0, 2.8.1, 3.0.0
> Reporter: Luke Chen
> Priority: Major
> Labels: newbie, newbie++
>
> Following the quickstart guide[1], when describing the topic just created
> with default config, I found there's a overridden config shown:
> _> bin/kafka-topics.sh --describe --topic quickstart-events
> --bootstrap-server localhost:9092_
> _Topic: quickstart-events TopicId: 06zRrzDCRceR9zWAf_BUWQ
> PartitionCount: 1 ReplicationFactor: 1 *Configs:
> segment.bytes=1073741824*_
> _Topic: quickstart-events Partition: 0 Leader: 0 Replicas: 0
> Isr: 0_
>
> This config result should be empty as in Kafka quick start page. Although the
> config value is what we expected (default 1GB value), this info display still
> confuse users.
>
> Note: I checked the 2.8.1 build, this issue also happened.
