Hi, I used this requirements.txt file to install airflow from the v1-10-test branch:
git+https://github.com/celery/celery@master#egg=celery git+https://github.com/apache/incubator-airflow@v1-10-test#egg=apache-airflow[celery,crypto,emr,hive,hdfs,ldap,mysql,postgres,redis,slack,s3] kombu>=4.1.0 In my airflow.cfg, I have: [celery] executor = CeleryExecutor executor = CeleryExec broker_url = sqla+mysql://airflow:blah@localhost:3306/mydb [celery_broker_transport_options] # # However, if I manually run this code inside the webserver, I see: python -c "from airflow import configuration; c = configuration.conf.getsection('celery_broker_transport_options'); print(c)" OrderedDict([(u'visibility_timeout', 21600), (u'ssl_active', False), (u'ssl_key', u''), (u'ssl_cert', u''), (u'ssl_cacert', u'')]) My worker crashes with this error: [2018-05-21 07:46:12,406] {configuration.py:212} WARNING - section/key [celery/ssl_active] not found in config [2018-05-21 07:46:12,407] {default_celery.py:51} WARNING - Celery Executor will run without SSL [2018-05-21 07:46:12,411] {__init__.py:48} INFO - Using executor CeleryExecutor [2018-05-21 07:46:13,086: CRITICAL/MainProcess] Unrecoverable error: TypeError(u"Invalid argument(s) 'ssl_key','ssl_cert','ssl_active','visibility_timeout','ssl_cacert' sent to create_engine(), using configuration MySQLDialect_mysqldb/QueuePool/Engine.

I thought that having an empty section in airflow.cfg would be enough? I thought that this was fixed with: https://github.com/apache/incubator-airflow/pull/2842 I cannot pass visibilty_timeout or ssl_key to a mysql backend. -- Craig
