             Summary: Update native spark metrics
                 Key: BEAM-5212
                 URL: https://issues.apache.org/jira/browse/BEAM-5212
             Project: Beam
          Issue Type: Improvement
          Components: runner-spark
            Reporter: Etienne Chauchot
            Assignee: Amit Sela


Native engine metrics are updated on {{finishBundle}} by DoFnRunners. Spark 
uses {{SimpleDoFnRunner}} that is in runner-core and thus contains nothing 
spark native. It might be good to extend {{SimpleDoFnRunner}} to add native 
metrics support just like it was done in Flink with {{DoFnRunnerWithMetrics}} 
class.
