Work Description: fredo838 commented on issue #8572: [BEAM-6429]
Addressing K,V coders in python 3.6
URL: https://github.com/apache/beam/pull/8572#issuecomment-492233519
This PR tries to find out why running `python setup.py nosetests --tests
apache_beam.runners.portability.fn_api_runner_test.py:FnApiRunnerTest.test_multimap_side_input`
fails with a `Not a KV coder: BytesCoder`. This is JIRA issue
[BEAM-6429](https://issues.apache.org/jira/browse/BEAM-6429). I went up the
stacktrace, and noticed that the transform containing the multimap didn't have
a `TupleCoder` (like in Python 3.5) as its coder, but a `FastPrimitivesCoder`.
This is in de `pipeline_proto` variable, which led me to
[here](https://github.com/apache/beam/blob/5c7ee600ba8560102f61622c894633955d208f87/sdks/python/apache_beam/pipeline.py#L638-L639).
