--------------------------------------

             Summary: Airflow webserver/scheduler don't handle database disconnects (mysql)
                 Key: AIRFLOW-1665
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1665
             Project: Apache Airflow
          Issue Type: Bug
    Affects Versions: Airflow 1.8
            Reporter: Vasanth Kumar


Airflow webserver & scheduler don't handle database disconnects.  The process appear to
error out and either exit or are left in an off state.  This was observed when using mysql.

I don't see any database reconnect configuration or code.

Stack tace for scheduler:
  File "...../MySQLdb/connections.py", line 204, in __init__
    super(Connection, self).__init__(*args, **kwargs2)
sqlalchemy.exc.OperationalError: (_mysql_exceptions.OperationalError) (2002, "Can't connect
to local MySQL server through socket '/tmp/mysql.sock' (2)")
