Hi,

Thanks very much for this PR. I started the job on Travis with this change.
https://travis-ci.org/GoogleCloudPlatform/oozie-to-airflow/builds/553850219
When the job is completed, I will merge a change to the project.

I have another task for you. This is a bit harder.
#266
Do you want to take it?

[LeonardoFurtado]

Yes I do. If i have any questions about what to do in #266 can I leave a comment on it? I intend to continue contributing whenever possible, over time I will better understand the structure of the project.

[mik-laj]

Yes. You can ask questions on the issues.

I'm also available on Slack - Apache Airflow. https://apache-airflow-slack.herokuapp.com/ I'm Kamil Breguła on this slack, but i prefer discussion over issues.
