------------------------------------
Summary: DAG with a relativedelta schedule_interval fails
Key: AIRFLOW-2231
URL: https://issues.apache.org/jira/browse/AIRFLOW-2231
Project: Apache Airflow
Issue Type: Bug
Components: DAG
Reporter: Kyle Brooks
The documentation for the DAG class says using
dateutil.relativedelta.relativedelta as a schedule_interval is supported but it
fails:
Traceback (most recent call last):

if schedule_interval in cron_presets:
TypeError: unhashable type: 'relativedelta'
It looks like the __init__ function for class DAG assumes the schedule_interval
is hashable.
