---------------------------------------------------------------
The documentation is actually wrong and I created another JIRA to get that
corrected:
https://issues.apache.org/jira/browse/KAFKA-6301
If you use * you'll see in the MirrorMaker's log that it starts up with a blank
whitelist parameter as opposed to using .* which shows up correctly.

> Project: Kafka
> Issue Type: Bug
> Components: tools
> Affects Versions: 0.11.0.0
> Reporter: Waleed Fateem
> Priority: Minor
>
> When using the regular expression .* for the whitelist parameter in Kafka
> MirrorMaker in order to mirror all topics, the MirrorMaker doesn't replicate
> any messages. I was then able to see messages flowing again and being
> replicated between the two Kafka clusters once I changed the whitelist
> configuration to use another regular expression, such as 'topic1 | topic2 |
> topic3'
