-------------------------------
Summary: Improve error message when adding a PTransform with a
name that already exists in the pipeline
Key: BEAM-8415
URL: https://issues.apache.org/jira/browse/BEAM-8415
Project: Beam
Issue Type: Improvement
Components: sdk-py-core
Reporter: David Yan
Currently, when trying to apply a PTransform with a name that already exists in
the pipeline, it returns a confusing error:
Transform "XXX" does not have a stable unique label. This will prevent updating
of pipelines. To apply a transform with a specified label write pvalue |
"label" >> transform
We'd like to improve this error message.
