Waleed Fateem commented on KAFKA-6408: -------------------------------------- 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. > 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' -- This message was sent by Atlassian JIRA (v6.4.14#64029)
