------------------------------------------
Summary: Enable Python3 tests on contrib Spark Submit Hook
Key: AIRFLOW-1393
URL: https://issues.apache.org/jira/browse/AIRFLOW-1393
Project: Apache Airflow
Issue Type: Bug
Components: tests
Reporter: Ash Berlin-Taylor
Priority: Minor
The unit tests in {{tests/contrib/hooks/test_spark_submit_hook.py}} currently
skip if run in Python3 because some test cases loop forever due to a
mismatch/misunderstanding about bytes vs string (i.e. the mocked data for
{{subprocess.Popen}} doesn't behave the same as actually running Popen)
The fix is to use bytes and {{six.ByteIO}} so that the tests work on Py2 and
Py3.
