Comment 3 for bug 1435444

In metadata.yaml you have 'repositories/ubuntu' specified as a path for Centos, change it to 'repositories/centos', I'm not sure if we can provide some validation for that, because several distribution can have any directories for repositories.

- os: centos
    version: 2014.2-6.1
    mode: ['ha', 'multinode']
    deployment_scripts_path: deployment_scripts/
    repository_path: repositories/ubuntu
