[jira] [Commented] (BEAM-6506) Dataflow runner harness should always use proper coder URNs

    [ https://issues.apache.org/jira/browse/BEAM-6506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16788064#comment-16788064 ] 

Kenneth Knowles commented on BEAM-6506:
---------------------------------------

There's not a component for the pieces of the Python codebase, quite, so just moving this to core.

> 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".
