Subject [jira] [Created] (BEAM-2499) Fail to merge Custom Windows in Spark runner
Date Thu, 22 Jun 2017 14:56:00 GMT
Etienne Chauchot created BEAM-2499:
--------------------------------------

             Summary: Fail to merge Custom Windows in Spark runner
                 Key: BEAM-2499
                 URL: https://issues.apache.org/jira/browse/BEAM-2499
             Project: Beam
          Issue Type: Bug
          Components: runner-spark
            Reporter: Etienne Chauchot
            Assignee: Amit Sela


If we extend {{IntervalWindow}} and we try to merge these custom windows like in this PR:
https://github.com/apache/beam/pull/3286
Then spark runner fails with 

{{org.apache.beam.sdk.Pipeline$PipelineExecutionException: java.lang.ClassCastException: org.apache.beam.sdk.transforms.windowing.IntervalWindow
cannot be cast to org.apache.beam.sdk.transforms.windowing.MergingCustomWindowsTest$CustomWindow}}

It seems to be because of the cast to {{IntervalWindow}} there: https://github.com/apache/beam/blob/master/runners/spark/src/main/java/org/apache/beam/runners/spark/translation/SparkGlobalCombineFn.java#L111
