> When writing a pipeline that authenticates with Google Dataflow APIs using a service account, specifying the path to that service account's credentials file in the {{PipelineOptions}} object passed in to the pipeline does not work, it only works when passed as a command-line flag.
> For example, if I write code like so:
> {code}
> pipelineOptions = options.PipelineOptions()
> gcOptions = pipelineOptions.view_as(options.GoogleCloudOptions)
> gcOptions.service_account_name = 'My Service Account Name'
> gcOptions.service_account_key_file = '/some/path/keyfile.p12'
> pipeline = beam.Pipeline(options=pipelineOptions)
> # ... add stages to the pipeline
> p.run()
> {code}
> and execute it like so:
> {{python ./my_pipeline.py}}
> ...the service account I specify will not be used.
> Only if I were to execute the code like so:
> {{python ./my_pipeline.py --service_account_name 'My Service Account Name' --service_account_key_file /some/path/keyfile.p12}}
> ...does it actually use the service account.
> The problem appears to be rooted in `auth.py` which reconstructs the {{PipelineOptions}} object directly from {{sys.argv}} rather than using the instance passed in to the pipeline: https://github.com/apache/incubator-beam/blob/9ded359daefc6040d61a1f33c77563474fcb09b6/sdks/python/apache_beam/internal/auth.py#L129-L130
