-----------------------------------------
Summary: MirrorMaker 2.0 documentation is incorrect
Key: KAFKA-12371
URL: https://issues.apache.org/jira/browse/KAFKA-12371
Project: Kafka
Issue Type: Bug
Components: docs, documentation
Affects Versions: 2.7.0
Reporter: Scott Kirkpatrick
There are a few places in the official MirrorMaker 2.0 docs that are either
confusing or incorrect. Here are a few examples I've found:
The documentation for the 'sync.group.offsets.enabled' config states that it's
enabled by default
[here|https://github.com/apache/kafka-site/blob/61f4707381c369a98a7a77e1a7c3a11d5983909c/27/ops.html#L802],
but the actual source code indicates that it's disabled by default
[here|https://github.com/apache/kafka/blob/f75efb96fae99a22eb54b5d0ef4e23b28fe8cd2d/connect/mirror/src/main/java/org/apache/kafka/connect/mirror/MirrorConnectorConfig.java#L185].
I'm unsure if the intent is to have it enabled or disabled by default.
There are also some numerical typos,
[here|https://github.com/apache/kafka-site/blob/61f4707381c369a98a7a77e1a7c3a11d5983909c/27/ops.html#L791]
and
[here|https://github.com/apache/kafka-site/blob/61f4707381c369a98a7a77e1a7c3a11d5983909c/27/ops.html#L793].
These lines state that the default is 6000 seconds (and that's equal to 10
minutes), but the actual default is 600 seconds, shown
[here|https://github.com/apache/kafka/blob/f75efb96fae99a22eb54b5d0ef4e23b28fe8cd2d/connect/mirror/src/main/java/org/apache/kafka/connect/mirror/MirrorConnectorConfig.java#L145]
and
