Trying to build debezium, MySQL test doesn't pass

[blind.lin...@gmail.com]

Hi, 

just getting started testing out debezium and I can't get the tests to pass out of the box. 

I have never used docker, so there may be a configuration error, but...I was able to successfully run through the tutorial on the website found here: http://debezium.io/docs/tutorial/  (which is great by the way.  Thanks to those who put the work in on that).

after checking out the source from github, mvn clean test fails with the following:


```

I downloaded debezium following the instructions on the github page.   git log says the commit is at

```
commit c04c5c9997ae70d1f118cd1cc732634874854179
Merge: 4b2b596 d42736e
Author: Randall Hauch <r...m>

```

I checked out tag 0.5.0  (commit 2bc3d459549f3c29959dce07fc7a9077c45e0315) and hit the exact same error.

 My prereqs are versioned as follows:

```
git version 2.11.0

javac 1.8.0_121

Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T08:41:47-08:00)
Maven home: /usr/share/maven
Java version: 1.8.0_121, vendor: Oracle Corporation
Java home: /usr/lib64/java/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "4.10.2", arch: "amd64", family: "unix"

Docker version 17.03.1-ce, build c6d412e
```

Where I think I'm making a mistake is that I don't really understand what is being asked in the README at https://github.com/debezium/debezium#configure-your-docker-environment

I am running docker on my laptop, and was able to get through the tutorial without any problems, but I don't know what the correct settings for the following environment variables should be:

```

export DOCKER_HOST=tcp://10.1.2.2:2376
export DOCKER_CERT_PATH=/path/to/cdk/.vagrant/machines/default/virtualbox/.docker
export DOCKER_TLS_VERIFY=1
```

I currently have NONE of these set ( running env | grep -i docker returns nothing)

Thanks for any advice on how to get this test to pass.  If it is a real bug, I'll file on the jboss bug site.
