---------------------------------

             Summary: FlinkRunner does not support Detached Mode
                 Key: BEAM-642
                 URL: https://issues.apache.org/jira/browse/BEAM-642
             Project: Beam
          Issue Type: Bug
          Components: runner-spark
            Reporter: Sumit Chawla
            Assignee: Amit Sela


When using {{JavaSerializer}} instead of {{KryoSerializer}} by configuring {{JavaSparkContext}}
with  {{"spark.serializer"}} set to {{JavaSerializer.class.getCanonicalName()}}, an exception
is thrown:

{noformat}
object not serializable (class: org.apache.beam.sdk.util.WindowedValue$ValueInGlobalWindow,
value: ValueInGlobalWindow{value=hi there, pane=PaneInfo.NO_FIRING})
{noformat}

This issue is reproducible with the {{SimpleStreamingWordCountTest#testRun}} test (given {{JavaSerialiser}}
is configured).
