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

             Summary: TransformHierarchy.Node getInputs() TupleTags doesn't match previous ParDo.MultiOutput's getOutputs().
                 Key: BEAM-2681
                 URL: https://issues.apache.org/jira/browse/BEAM-2681
             Project: Beam
          Issue Type: Bug
          Components: sdk-java-core
            Reporter: Pei He
            Assignee: Thomas Groh
            Priority: Minor


For example,
ParDo.MultiOutput ->PCollectionTuple [tag1 -> pc1 (tag_pc1), tag2 -> pc2 (tag_pc2)]
pc1 (tag_pc1) -> transform_a
pc2 (tag_pc2) -> transform_b

During translation, calling getOutputs() for Node ParDo.MultiOutput will returns map keyed by tag1 and tag2, and calling getInputs() for Node transform_a and transform_b will returns map keyed by tag_pc1 and tag_pc2 respectively.

Every runner will need to add special case for ParDo translation in order to handle this.
Is this a bug or intended? (If it is intended, should we document it somewhere for runner implementors?)
