How to setup inter DC replication in Kafka 0.8.1.1

Hi,

I want to setup inter DC replication b/w Kafka clusters. Is there any
inbuilt tool to do this?

I already have tried MirrorMaker tool but the problem is, if MM killed then
some messages get duplicated. I don't want to duplicate the messages.

Please suggest a way to do this. Please share your experience how you have
setup this.

Thanks in Advance,
Madhukar
