Tushar Bhasme commented on KAFKA-10704:
---------------------------------------
Sorry, I forgot to update this bug. We were able to find the correct
configuration to make it work. It would have been great if all the
configurations for mm2 were well documented, maybe it is but I don't know
where. I had to debug through the code to get the correct nomenclature. Correct
configuration that worked for us was:
{code:java}
clusters = A, B
B.security.protocol=SSL
B.ssl.truststore.location=client.truststore
B.ssl.truststore.password=123456
B.ssl.keystore.location=client.keystore
B.ssl.keystore.password=123456
B.ssl.key.password=123456 {code}

> Key: KAFKA-10704
> URL: https://issues.apache.org/jira/browse/KAFKA-10704
> Project: Kafka
> Issue Type: Bug
> Components: mirrormaker
> Affects Versions: 2.6.0
> Reporter: Tushar Bhasme
> Priority: Critical
> Fix For: 2.7.0
>
>
> We need to setup mirror maker from a single node kafka cluster to a three
> node Strimzi cluster. There is no SSL setup at source, however the target
> cluster is configured with MTLS.
> With below config, commands from source like listing topics etc are working:
> {code:java}
> cat client-ssl.properties
> security.protocol=SSL
> ssl.truststore.location=my.truststore
> ssl.truststore.password=123456
> ssl.keystore.location=my.keystore
> ssl.keystore.password=123456
> ssl.key.password=password{code}
> However, we are not able to get mirror maker working with the similar configs:
> {code:java}
> source.security.protocol=PLAINTEXT
> target.security.protocol=SSL
> target.ssl.truststore.location=my.truststore
> target.ssl.truststore.password=123456
> target.ssl.keystore.location=my.keystore
> target.ssl.keystore.password=123456
> target.ssl.key.password=password{code}
