             Summary: Dataflow runner harness should always use proper coder URNs
                 Key: BEAM-6506
                 URL: https://issues.apache.org/jira/browse/BEAM-6506
             Project: Beam
          Issue Type: Wish
          Components: runner-core
            Reporter: Mark Liu
            Assignee: Robert Bradshaw


This comes from a Python 3 incompatible bug and mentioned in https://github.com/apache/beam/pull/7521/files#r248993766. The fix decode payload unconditionally in Python 2 or 3 but suggested by [~robertwb]: 

"the Dataflow runner harness was fixed to always use proper coder URNs rather than stuffing json-ized dataflow v1b3 cloud proto representations into the payload".
