[jira] [Created] (BEAM-8894) Fix multiple coder bug in new spark runner

Etienne Chauchot created BEAM-8894:
--------------------------------------

             Summary: Fix multiple coder bug in new spark runner
                 Key: BEAM-8894
                 URL: https://issues.apache.org/jira/browse/BEAM-8894
             Project: Beam
          Issue Type: Bug
          Components: runner-spark
            Reporter: Etienne Chauchot
            Assignee: Etienne Chauchot


The test below does not pass. I fails with an EOF while calling NullableCoder(BigEndianCoder.decode) 

'org.apache.beam.sdk.transforms.FlattenTest.testFlattenMultipleCoders'

In the "old" spark runner, this test passes because it never call the NullableCoder because there is no serialization done. 

There may be a problem in the NullableCoder itself
