Multiple consumer.config gives error Found multiple arguments for option consumer.config

[Data WizApp]

We are trying to start mirror maker with the following configuration : 

/bin/kafka-run-class kafka.tools.MirrorMaker --consumer.config config/slave-1/consumer.properties --consumer.config config/slave-2/consumer.properties --producer.config config/producer.properties --whitelist 'topic' &

I am getting following error :

 [2016-08-24 14:02:13,132] ERROR Exception when starting mirror maker. (kafka.tools.MirrorMaker$)

joptsimple.MultipleArgumentsForOptionException: Found multiple arguments for option consumer.config, but you asked for only one

Exception in thread "main" java.lang.NullPointerException

There is some error in configuration of MirrorMaker, any update by anyone?

I believe the support for multiple consumer configs was dropped somewhere. So you should start two mirror makers if you want to consume with two different configurations
