------------------------------------
Summary: Unable to start webserver using systemd script
Key: AIRFLOW-166
URL: https://issues.apache.org/jira/browse/AIRFLOW-166
Project: Apache Airflow
Issue Type: Bug
Affects Versions: Airflow 1.7.1
Environment: CentOS 7
Reporter: Yuri Bendana
I just upgraded to 1.7.1.2 from 1.6 and I'm having a problem starting the
webserver using the systemd script. This used to work fine. The issue is that
it starts and then just hangs, no error is reported and it finally times out
after about a minute. I tried starting it from the command line and it works
fine without timing out. I also ran it in daemon mode with -D and again it
seems to be fine. Any thoughts on how to debug this?
Here's the log output:
