-------------------------------
Summary: WindowedValue$ValueInGlobalWindow is not serializable
when using JavaSerializer instead of Kryo
Key: BEAM-637
URL: https://issues.apache.org/jira/browse/BEAM-637
Project: Beam
Issue Type: Bug
Components: runner-spark
Reporter: Stas Levin
Assignee: Amit Sela
When using {{JavaSerializer}} instead of {{KryoSerializer}} by configuring
{{JavaSparkContext}} with {{"spark.serializer"}} set to
{{JavaSerializer.class.getCanonicalName()}}, an exception is thrown:
{noformat}
object not serializable (class:
org.apache.beam.sdk.util.WindowedValue$ValueInGlobalWindow, value:
ValueInGlobalWindow{value=hi there, pane=PaneInfo.NO_FIRING})
{noformat}
{noformat}
Serialization stack:
- object not serializable (class:
org.apache.beam.sdk.util.WindowedValue$ValueInGlobalWindow, value:
ValueInGlobalWindow{value=hi there, pane=PaneInfo.NO_FIRING})
