Siro commented on AIRFLOW-2009:
-------------------------------

I encountered this too.

How did you work around this? Did you change the hook code manually?

>             Project: Apache Airflow
>          Issue Type: Bug
>          Components: Dataflow, hooks
>    Affects Versions: 2.0.0

>            Priority: Major

> We have been using the DataFlowOperator to schedule DataFlow jobs.
> We found that the DataFlowHook used by the DataFlowOperator doesn't actually use the passed `gcp_conn_id` to schedule the DataFlow job, but only to read the results after. 
> code (https://github.com/apache/incubator-airflow/blob/master/airflow/contrib/hooks/gcp_dataflow_hook.py#L158):
>         _Dataflow(cmd).wait_for_done()
>         _DataflowJob(self.get_conn(), variables['project'],
>                      name, self.poll_sleep).wait_for_done()
> The first line here should also be using self.get_conn(). 
> For this reason, our tasks using the DataFlowOperator have actually been using the default Google Compute Engine service account (which has DataFlow permissions) to schedule DataFlow jobs. It is only when our provided service account (which does not have DataFlow permissions) is used in the second line that we are seeing a permissions error. 
> I would like to fix this bug, but have to work around it at the moment due to time constraints.
