XD-DENG opened a new pull request #4504: [AIRFLOW-3690] Fix api.common.experimental.mark_tasks.set_state for manually-triggered DAG Runs
URL: https://github.com/apache/airflow/pull/4504
 
 
   ### Jira
   
     - https://issues.apache.org/jira/browse/AIRFLOW-3690
   
   ### Description
   
   `set_state` function removes microsecond information from the exectution_date before
   further query from the database. However, microsecond is stored in the task_instance table. So all task instances of manually-triggered DAG Runs can not be queried successfully inside the set_state function.
   
   The result is: for all the manually-triggered DAG Runs, if users try to mark state of a task instance, it will fail because no corresponding records can be found. 
   
   This doesn't impact any scheduled DAG Runs since the microsecond in their execution_date is 0.
