How to set up emr_default in airflow

Question

Dear Stackoverflow member,

I am trying to use Airflow to schedule a DAG that launch a cluster, run some spark jobs then terminated itself. I tried to follow this example: https://insight.io/github.com/apache/incubator-airflow/blob/master/airflow/contrib/example_dags/example_emr_job_flow_automatic_steps.py

It gave me the error: airflow.exceptions.AirflowException: The conn_id emr_default isn't defined

I probably need to have emr_default set up (please correct me if this is not the case). Does anyone have try this before and give me some hints on how to set it up? Airflow website doesn't provide too much on emr connection: http://pythonhosted.org/airflow/configuration.html?highlight=connection#connections

Thanks!

Answer 1

On the airflow UI, go to Admin -> Connections tab, and edit the values for emr_default row.

Answer 2

As@Him said, you can edit in airflow. but if you can't find emr_default, you can go to Admin -> Connections -> Create to add any connection you want
