             Summary: Apache Nemo quickstart broken for Apache Beam 2.16 and 2.17 due to backwards incompatible change in ParDo.getSideInputs
                 Key: BEAM-8989
                 URL: https://issues.apache.org/jira/browse/BEAM-8989
             Project: Beam
          Issue Type: Bug
          Components: sdk-java-core
    Affects Versions: 2.16.0, 2.17.0, 2.18.0
            Reporter: Luke Cwik
            Assignee: Mikhail Gryzykhin


This changed `ParDo.getSideInputs` from `List<PCollectionView>` to `Map<String, PCollectionView>` which is backwards incompatible change and was released as part of Beam 2.16.0 erroneously.
