[jira] [Commented] (AIRFLOW-5071) Thousand os Executor reports task instance X finished (success) although the task says its queued. Was the task killed externally?

    [ https://issues.apache.org/jira/browse/AIRFLOW-5071?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17024541#comment-17024541 ] 

Ignacio Peluffo commented on AIRFLOW-5071:
------------------------------------------

Another one here, below is a capture of Flower showing that a task was scheduled multiple times (the capture shows only three but there were 21 schedules):

Then, in the database's table `task_instance`, the tasks row looks like:

 
{code:java}
+----------------------+-----------------+----------------------------+------------+----------------------------+----------+--------+------------+----------+----------+--------+--------------+---------+-----------------+----------+----------------------------+------+-----------+------------------+
| task_id              | dag_id          | execution_date             | start_date | end_date                   | duration | state  | try_number | hostname | unixname | job_id | pool         | queue   | priority_weight | operator | queued_dttm                | pid  | max_tries | executor_config  |

{code}
I hope this help to find the cause and solution to the problem.

Also, any recommendation about which setting could be changed to fix this issue would be appreciate it.

> I'm opening this issue because since I update to 1.10.3 I'm seeing thousands of daily messages like the following in the logs:
>  
> ```
>  {{__init__.py:1580}} ERROR - Executor reports task instance <TaskInstance: X 2019-07-29 00:00:00+00:00 [queued]> finished (success) although the task says its queued. Was the task killed externally?
> {{jobs.py:1484}} ERROR - Executor reports task instance <TaskInstance: X 2019-07-29 00:00:00+00:00 [queued]> finished (success) although the task says its queued. Was the task killed externally?
> ```
> -And looks like this is triggering also thousand of daily emails because the flag to send email in case of failure is set to True.-
> I have Airflow setup to use Celery and Redis as a backend queue service.
