Waleed Fateem commented on KAFKA-6408:
--------------------------------------
Just closing the loop here. This is only an issue when you configure Kafka
using the Cloudera Manager UI. The problem is with Cloudera Manager and not
Kafka, where it's not parsing the regular expression correctly.
Marking as resolved.
> Kafka MirrorMaker doesn't replicate messages when .* regex is used

> Key: KAFKA-6408
> URL: https://issues.apache.org/jira/browse/KAFKA-6408
> 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'
