 To run the integration test, you need a Linux with Kernel version >= 3.10 and Docker 1.7 (or higher). The test framework will use several Docker images.
 These docker image **NEED** to be prepared **BEFOREHAND** to avoid timeout during testing:
 
- * [The Gearpump Cluster Launcher and Storm Client](https://hub.docker.com/r/grubykarol/gearpump-launcher/)
-   `docker pull grubykarol/gearpump-launcher`
  * [The standalone single node Kafka cluster with Zookeeper](https://hub.docker.com/r/grubykarol/kafka/)
    `docker pull grubykarol/kafka:0.8.2.1`
  * [The Hadoop image](https://hub.docker.com/r/sequenceiq/hadoop-docker/)

+3. Build Gearpump docker image 
+   `docker build -t gearpump/gearpump-launcher integrationtest/docker/gearpump`
+4. Run Integration test
    `sbt it:test`
 
 The test will launch a Gearpump cluster with 1 master and 2 worker nodes as 3 Docker containers. It might take 10-20 minutes to go through all the test cases. It depends on, how powerful your machine is. The Docker container itself does not have a Gearpump distribution. It will link your local build to the Docker container. When tests are finished, you can see the test result on the screen, or you can save them to a file with this command `sbt it:test > test_report.out`. To investigate Gearpump log, please check the directory `output/target/pack/logs`.
