Umesh Chaudhary commented on KAFKA-6408:
----------------------------------------

How about using {{--whitelist '*'}} as mentioned in the 
[docs|http://kafka.apache.org/0110/documentation.html#basic_ops_mirror_maker]

> Kafka MirrorMaker doesn't replicate messages when .* regex is used

> 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'
