I use HDP 2.6.3 with Kafka and Storm. When i try to upload a topology the warning below is appeared. I use kafka client, storm client and so on with minor versions 2.6.3 (the same as the cluster versions).

@Ivan Mladenov

Looks like you are using the consumer properties in producer and hence kafka is ignoring.

Refer : https://kafka.apache.org/0100/documentation.html for all valid configs for the version you are using.
