[jira] [Updated] (AIRFLOW-4547) Negative priority_weight should not be permitted

     [ https://issues.apache.org/jira/browse/AIRFLOW-4547?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Teresa Martyny updated AIRFLOW-4547:
------------------------------------
    Description: 
Airflow allows a dev to assign a negative priority_weight to a task. However, the Airflow code does math to determine the priority_weight on its own in models.py#priority_weight_total on line 2796

This makes the final priority_weight wrong in the end. Airflow should raise an error if an operator has priority_weight assigned to a negative number at any point.
