-------------------------------------
Summary: Job does not find CONN_ID environmental variable
Key: AIRFLOW-253
URL: https://issues.apache.org/jira/browse/AIRFLOW-253
Project: Apache Airflow
Issue Type: Bug
Components: hooks
Affects Versions: 1.7.1.3
Environment: OS: Ubuntu 14.04
airflow@ip-10-0-40-185:~$ pip show airflow
---
Name: airflow
Version: 1.7.1.3
Reporter: Nathan Scully
I am not sure if this is directly an airflow issue or something causing havoc
in my environment but when the scheduler triggers a test job I have setup
(@hourly) to ping a Redshift server with a 'select * from x limit 1;' I receive
a no conn_id found. However, I can echo the environmental var and if I run the
job as a test, or manually query from python console I can resolve it. Any
ideas what might be causing it to be missed?
Error from AIRFLOW scheduled run:

I can echo the env variable:

airflow@ip-xx-x-xx-xxx:~$ echo $AIRFLOW_CONN_OF_REDSHIFT
postgres://airflow:xxx@xxx:5439/xxx

And can also get it through python console:
