Subject [jira] [Created] (AIRFLOW-210) sqlalchemy warns about task_instance.execution_date invoked with an empty sequence
Date Fri, 03 Jun 2016 15:13:59 GMT
Eric Johnson created AIRFLOW-210:
------------------------------------

             Summary: sqlalchemy warns about task_instance.execution_date invoked with an
empty sequence
                 Key: AIRFLOW-210
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-210
             Project: Apache Airflow
          Issue Type: Bug
          Components: scheduler
    Affects Versions: Airflow 1.7.0
         Environment: Linux, python 2.7, and mysql 5.5.47
            Reporter: Eric Johnson
            Priority: Minor


On a fresh installation of airflow, I'm noticing this warning while running the scheduler.
I'm using mysql as the storage for airflow.

{{/opt/packages/python/2.7.5/lib/python2.7/site-packages/sqlalchemy/sql/default_comparator.py:153:
SAWarning: The IN-predicate on "task_instance.execution_date" was invoked with an empty sequence.
This results in a contradiction, which nonetheless can be expensive to evaluate.  Consider
alternative strategies for improved performance.}}
