----------------------------------
Summary: GCP Dataflow hook should specifically run python2
Key: AIRFLOW-2988
URL: https://issues.apache.org/jira/browse/AIRFLOW-2988
Project: Apache Airflow
Issue Type: Improvement
Components: Dataflow, gcp, hooks
Reporter: Jimmy Cao
Currently the GCP dataflow hook invokes 'python'
[here|https://github.com/apache/incubator-airflow/blob/c3939c8e721870d263997e7aeaebc28e678d544b/airflow/contrib/hooks/gcp_dataflow_hook.py#L239].
This can fail if the user's 'python' in PATH starts python 3, which Apache
Beam does not yet support, (see BEAM-1251).
It should be changed to 'python2' to ensure that Apache Beam is run with the
correct version of Python.
