> Key: KAFKA-12371
> URL: https://issues.apache.org/jira/browse/KAFKA-12371

> Reporter: Scott Kirkpatrick
> Priority: Minor

> 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 incorrectly that it'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 [here|https://github.com/apache/kafka/blob/f75efb96fae99a22eb54b5d0ef4e23b28fe8cd2d/connect/mirror/src/main/java/org/apache/kafka/connect/mirror/MirrorConnectorConfig.java#L152]
