Anbumani Balusamy commented on CAMEL-9818:
------------------------------------------

[~ancosen]/[~jlpedrosa]

All the Properties which are emitted in log as Warning message are related to 
Kafka version 0.9. Security features were added starting from Kafka 0.9 version 
only. Please refer this link for 
http://kafka.apache.org/documentation.html#security more info

Thanks!
