--------------------------------------

             Summary: File DynamicDestinations side inputs don't work with sharding
                 Key: BEAM-2753
                 URL: https://issues.apache.org/jira/browse/BEAM-2753
             Project: Beam
          Issue Type: Bug
          Components: sdk-java-core
            Reporter: Eugene Kirpichov
            Assignee: Reuven Lax


WriteWithShardingFactory uses PTransformReplacements.getSingletonMaininput https://github.com/apache/beam/blob/master/runners/direct-java/src/main/java/org/apache/beam/runners/direct/WriteWithShardingFactory.java#L74

However if the dynamic destinations have a side input, then the transform has more than 1
input and the function fails:

Exception in thread "main" java.lang.IllegalArgumentException: Got multiple inputs that are
not additional inputs for a singleton main input: Avro schema side input/ParMultiDo(Anonymous).out0
[PCollection] and Run read all/Execute queries/ParMultiDo(NaiveSpannerRead).out0 [PCollection]

	at org.apache.beam.sdk.Pipeline.run(Pipeline.java:289)

This is not caught by unit tests because unit tests specify withoutSharding().
