--------------------------------------
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.
