------------------------------------
Summary: Worker fails to connect with MySQL DB
Key: AIRFLOW-2631
URL: https://issues.apache.org/jira/browse/AIRFLOW-2631
Project: Apache Airflow
Issue Type: Bug
Affects Versions: Airflow 2.0, 1.10
Reporter: kunal gupta
I have containerized Airflow webserver, scheduler, flower and worker. I'm using
MySQL for the backend and Redis for queuing. Everytime I spin up the worker
node it throws the error below and all the Dags are stuck in running status.
Logs from the Worker Node:
File "/usr/lib64/python2.7/site-packages/MySQLdb/connections.py", line 193, in
__init__
super(Connection, self).__init__(*args, **kwargs2)
OperationalError: (_mysql_exceptions.OperationalError) (2002, "Can't connect to
local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)")
[2018-06-15 10:21:56,005: ERROR/MainProcess] Pool callback raised exception:
OperationalError('(_mysql_exceptions.OperationalError) (2002, "Can\'t connect
to local MySQL server through socket \'/var/lib/mysql/mysql.sock\' (2)")',)
