[jira] [Created] (BEAM-7448) Clean spark windowing

Etienne Chauchot created BEAM-7448:
--------------------------------------

             Summary: Clean spark windowing
                 Key: BEAM-7448
                 URL: https://issues.apache.org/jira/browse/BEAM-7448
             Project: Beam
          Issue Type: Improvement
          Components: runner-spark
            Reporter: Etienne Chauchot
            Assignee: Etienne Chauchot


In some places the Spark runner uses both external windowing and internal windowing in collections such as 
{code:java}
WindowedValue<KV<K, Iterable<WindowedValue<V>>>>
{code}
leading to unneeded mappers and dereference
The external windowing information is duplicated so unneeded
