                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1773

- When I click [Mark Success], there is no task instances

so I try to find what is problem. and i can find somthing wrong.

airflow / api / common / experimental / mark_tasks.py

{code:python}
def set_state(task, execution_date, upstream=False, downstream=False,
              future=False, past=False, state=State.SUCCESS, commit=False):
...
    if dag.schedule_interval == '@once':
        dates = [start_date]
    else:
        dates = dag.date_range(start_date=start_date, end_date=end_date)
...
    # verify the integrity of the dag runs in case a task was added or removed
    # set the confirmed execution dates as they might be different
    # from what was provided
    confirmed_dates = []
    drs = DagRun.find(dag_id=dag.dag_id, execution_date=dates)
    for dr in drs:
        dr.dag = dag
        dr.verify_integrity()
        confirmed_dates.append(dr.execution_date)
{code}

the drs is empty. because DagRun.find() with 'execution_date' is find same in DagRuns exactly. but, dag.date_range() make times upper second like 

[...datetime.datetime(2017, 11, 1, 11, 30), datetime.datetime(2017, 11, 1, 12, 0), dateti
me.datetime(2017, 11, 1, 12, 30), datetime.datetime(2017, 11, 1, 13, 0), datetime.datetime(2
017, 11, 1, 13, 30), datetime.datetime(2017, 11, 1, 14, 0)...]

!22.PNG|thumbnail!

so DagRun.find() can not find dags.
