Alex Guziel created AIRFLOW-1038: ------------------------------------ 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
