 The integration tests will actually start up real local Zookeeper
 instance and Kafka brokers, and send messages in using the client.

+First, get the kafka binaries for integration testing:
 ```shell
-.gradle/
-clients/build/
-contrib/build/
-contrib/hadoop-consumer/build/
-contrib/hadoop-producer/build/
-core/build/
-core/data/
-examples/build/
-perf/build/
-```

-First, check out and the Kafka source:
-```shell
-git submodule update --init
 ./build_integration.sh
 ```
