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

This also causes issues when different versions of celery are running on
different hosts.
