Pablo Estrada updated BEAM-3887:
--------------------------------
Resolution: Fixed
Status: Resolved (was: Open)
> Python SDK harness retrieves element codes from gRPC read/write nodes
> ---------------------------------------------------------------------
>
> Key: BEAM-3887
> URL: https://issues.apache.org/jira/browse/BEAM-3887
> Project: Beam
> Issue Type: Sub-task
> Components: sdk-py-core
> Reporter: Ben Sidhom
> Priority: P3
>
> The python harness does not correctly get coders from the gRPC read/write
> transforms but rather from PCollection inputs/outputs. This prevents the
> harness from correctly receiving/transmitting prefix-encoded elements (seen
> as prefix-encoded byte arrays by the runner).
> It should instead retrieve input and output coders from the gRPC nodes.
