[jira] [Created] (BEAM-11094) Only work with fully expanded PCollections in TransformHierarchy and PTransformReplacements

Kenneth Knowles created BEAM-11094:
--------------------------------------

             Summary: Only work with fully expanded PCollections in TransformHierarchy and PTransformReplacements
                 Key: BEAM-11094
                 URL: https://issues.apache.org/jira/browse/BEAM-11094
             Project: Beam
          Issue Type: Improvement
          Components: sdk-java-core
            Reporter: Kenneth Knowles
            Assignee: Kenneth Knowles


While developing #13053 I discovered that some output replacements were not being re-wired correctly. The current types in output replacements would allow false misses when two PValues were not expanded to the same degree. Fully expanding all PValues to PCollections is always allowed, always correct, and eliminates this class of errors.
