---------------------------------------
Summary: Java transform executed as Python transform?
Key: BEAM-10020
URL: https://issues.apache.org/jira/browse/BEAM-10020
Project: Beam
Issue Type: Bug
Components: jobserver, runner-flink
Affects Versions: 2.21.0
Reporter: Pawel Urbanowicz
Hey, I created a transform method in Java and now I want to use it in Python
using Cross-language. I got pretty stuck with the following problem:
*p*
*| GenerateSequence(...)*
*|ExternalTransform(...) => is working like a charm*
*p*
*| Create(...)*
*| ExternalTransform(...) => getting assert pardo_payload.do_fn.urn ==
python_urns.PICKLED_DOFN_INFO*
Based on [https://www.mail-archive.com/user@beam.apache.org/msg04887.html]
it seems like a Create transform is being registered as a Java transform but
executed as Python transform.
