timeout not working in SqlSensor?

[Scott Halgrim]

Does the timeout param work the way I think it should in Airflow 1.8? My query 
just pokes at the poke interval indefinitely. I want it to timeout after a few 
hours and fail instead.

The code is basically

“””
task_name = SqlSensor(
   conn_id='redshift',
   sql=(
       """
         select * from this_table where date=‘2018-12-18'
     """
   ),
   task_id=’task_name',
   dag=dag,
   start_date=datetime(2016, 9, 25),
   poke_interval=20,
   time_out=45,
“”"
So after running the query a couple of times I would expect a failure, but 
that’s not what’s happening, it just keeps querying and querying every 20 
seconds.

Thanks,

Scott
