Tushar Bhasme resolved KAFKA-10704.
-----------------------------------
Resolution: Not A Problem
> Mirror maker with TLS at target
> -------------------------------
>
> 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}
> Errors while running mirror maker:
