Brian Herman commented on AIRFLOW-878:
--------------------------------------
You can fix this by editing cli.py:
change this from:
run_args = [
'gunicorn',
'-w', str(num_workers),
'-k', str(args.workerclass),
'-t', str(worker_timeout),
'-b', args.hostname + ':' + str(args.port),
'-n', 'airflow-webserver',
'-p', str(pid),
'-c', 'airflow.www.gunicorn_config'
]
to this:
run_args = [
'/home/mbarkhau/testproject/venv/bin/gunicorn',
'-w', str(num_workers),
'-k', str(args.workerclass),
'-t', str(worker_timeout),
'-b', args.hostname + ':' + str(args.port),
'-n', 'airflow-webserver',
'-p', str(pid),
'-c', 'airflow.www.gunicorn_config'
]
