Description

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:

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

However, we are not able to get mirror maker working with the similar configs:

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
