[jira] [Commented] (AIRFLOW-3032) _pickle.UnpicklingError with
using remote MySQL Server
[ https://issues.apache.org/jira/browse/AIRFLOW-3032?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16623542#comment-16623542 ]
Fokko Driesprong commented on AIRFLOW-3032:
-------------------------------------------
[~MaxRichter] Would it be possible to check this with Airflow 1.10? A remove MySQL should not differ from a local MySQL I'd say.

> Key: AIRFLOW-3032
> URL: https://issues.apache.org/jira/browse/AIRFLOW-3032
> Project: Apache Airflow
> Issue Type: Bug
> Components: database
> Affects Versions: 1.9.0
> Reporter: Max Richter
> Priority: Blocker
> Attachments: error_log.txt, pip_list.txt
>
>
> Hello,
> I am running Airflow 1.9.0 successfully with a localhost MySQL database, version 5.7.23.
> I switched sql_alchemy_conn = mysql://airflow:<password>@<remote-host>:3306/airflow in order to use the proper MySQL server - same version 5.7.23.
> I created a dump from my local instance to the remote one.
> Issue:
> * When tasks are executed by the scheduler everything runs fine, tasks are executed and DB updated
> * When manually triggering a task via the webserver, I am getting "_pickle.UnpicklingError" please see error__log.txt for full log
> In the end, I only changed this one line in airflow.cfg which is causing that I can not use it with a remote MySQL server.
>
> Best,
> Max
