--------------------------------------
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}
Exception in thread "main" java.lang.IllegalStateException: No
