             Summary: Add support for PCollectionView in spark runner in streaming mode
                 Key: BEAM-2112
                 URL: https://issues.apache.org/jira/browse/BEAM-2112
             Project: Beam
          Issue Type: New Feature
          Components: runner-spark
            Reporter: Etienne Chauchot
            Assignee: Amit Sela


As a test, Nexmark query7 can be used
run Nexmark query7 (https://github.com/iemejia/beam/tree/BEAM-160-nexmark) in streaming mode using Spark.
Run main in
{code}org.apache.beam.integration.nexmark.drivers.NexmarkSparkDriver{code}
with VMOptions:
{code} -Dspark.ui.enabled=false -DSPARK_LOCAL_IP=localhost -Dsun.io.serialization.extendedDebugInfo=true {code}
with Program arguments:
{code}--query=7  --streaming=true --numEventGenerators=4 --manageResources=false --monitorJobs=true --enforceEncodability=false --enforceImmutability=false{code}
StackTrace is 
{code}
