dimon222 opened a new issue #9148:
URL: https://github.com/apache/airflow/issues/9148
**Apache Airflow version**:
1.10.10
**Database version**:
MariaDB
**What happened**:
When task fails, next task retry raises this exception immediately:
<details><summary>INSERT INTO rendered_task_instance_fields (dag_id,
task_id, execution_date, rendered_fields) VALUES (%s, %s, %s, %s)
('test_dag', 'test_task', datetime.datetime(2020, 6, 4, 22, 20, 21, 139775),
'')
_mysql_exceptions.IntegrityError: (1062, "Duplicate entry
'test_dag-test_task-2020-' for key 'PRIMARY')</summary></details>
For some reason the value for execution date is calculated exactly same as
previous retry. I might assume its not supposed to happen.
**What you expected to happen**:
Task retries correctly.
**How to reproduce it**:
Crash task that has retries > 1, wait for retry.
Alternatively, crash task, then clear this task's state in dag view to cause
manual retry.
**Anything else we need to know**:
It happens always on retry. Not happening on 1.10.9 (very recent regression)
I'm able to retry correctly by removing related task records in MariaDB in
rendered_task_instance_fields table.
