[jira] [Created] (BEAM-3369) Python HEAD fails tests due to a ValueError

Chamikara Jayalath created BEAM-3369:
----------------------------------------

             Summary: Python HEAD fails tests due to a ValueError 
                 Key: BEAM-3369
                 URL: https://issues.apache.org/jira/browse/BEAM-3369
             Project: Beam
          Issue Type: Bug
          Components: sdk-py-core
    Affects Versions: Not applicable
            Reporter: Chamikara Jayalath
            Assignee: Robert Bradshaw
            Priority: Critical


tfidf_test.py is failing. Full error message is given below.

ValueError: The key coder "TupleCoder[BytesCoder, FastPrimitivesCoder]" for GroupByKey operation "GroupByKey" is not deterministic. This may result in incorrect pipeline output. This can be fixed by adding a type hint to the operation preceding the GroupByKey step, and for custom key classes, by writing a deterministic custom Coder. Please see the documentation for more details.

Seems to be due to following commit (passes without that).
