Etienne Chauchot created BEAM-2029:
--------------------------------------
Summary: NullPointerException while evaluating GroupByKey in Spark Runner in streaming mode
Key: BEAM-2029
URL: https://issues.apache.org/jira/browse/BEAM-2029
Project: Beam
Issue Type: Bug
Components: runner-spark
Reporter: Etienne Chauchot
Assignee: Amit Sela
To reproduce the bug, run Nexmark query7 (https://github.com/iemejia/beam/tree/BEAM-160-nexmark)
Run main in {{org.apache.beam.integration.nexmark.drivers.NexmarkSparkDriver}}
with VMOptions: {code} -Dspark.ui.enabled=false -DSPARK_LOCAL_IP=localhost -Dsun.io.serialization.extendedDebugInfo=true {code}
with Program arguments:
{code}
--query=7 --streamTimeout=1200 --streaming=true --numEventGenerators=4 --manageResources=false --monitorJobs=true --enforceEncodability=false --enforceImmutability=false
{code}
Behavior:
{{context.borrowDataset(transform)}} returns null.
