------------------------------------

             Summary: Specify celery serializers explicitly
                 Key: AIRFLOW-1038
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1038
             Project: Apache Airflow
          Issue Type: Bug
            Reporter: Alex Guziel
            Assignee: Alex Guziel


Celery 3->4 upgrade changes the default task and result serializer from pickle to json.
Pickle is faster and supports more types http://docs.celeryproject.org/en/latest/userguide/calling.html
This also causes issues when different versions of celery are running on different hosts.
