0.8, the release in which added replication, was our first backwards-incompatible release: major changes were made to the API, ZooKeeper data structures, and protocol, and configuration. The upgrade from 0.7 to 0.8.x requires a special tool for migration. This migration can be done without downtime.
Since they changed the protocols I doubt that our client API can read from the old brokers.

We tested it only with Kafka 0.8.1 upwards.
I know nobody that used it with Kafka < 0.8 before. You can give it a try, let us know if it works...
BTW: I think Kafka 0.7 has so many open problems, if you can, may be worth upgrading...

Hej,
I want to connect Flink streaming to a Kafka 0.7 cluster.
Will this work with the latest release or does the Kafka implementation rely on kafka 0.8?
