Description

I am trying to run Mirror maker over SSL. I have configured my broker following the procedure described in this document http://kafka.apache.org/documentation.html#security_overview

I get the following warning when I start the mirror maker:

[root@munkhan-kafka1 kafka_2.10-0.9.0.1]# bin/kafka-run-class.sh kafka.tools.MirrorMaker --consumer.config config/datapush-consumer-ssl.properties --producer.config config/datapush-producer-ssl.properties --num.streams 2 --whitelist test1&

However the Mirror maker is able to mirror data . If I remove the configurations related to the warning messages from my producer mirror maker does not work . So it seems despite the warning shown above the ssl.configuration properties are used somehow.

My question is these are those warnings harmless in this context ?
