-------------------------------
Summary: UnboundedDataset action() does not materialize RDD
Key: BEAM-1636
URL: https://issues.apache.org/jira/browse/BEAM-1636
Project: Beam
Issue Type: Bug
Components: runner-spark
Reporter: Aviem Zur
Assignee: Aviem Zur
{{UnboundedDataset#action}} does not materialize DStream since it uses
{{register}}. Instead use {{foreachRDD}}...{{foreach}} which is an action,
which will materialize the RDDs of the DStream.
The reason it worked until now was because there was also a call to {{cache()}}
before it.
