[jira] [Created] (BEAM-6894) ExternalTransform.expand() does not create the proper AppliedPTransform sub-graph

Chamikara Jayalath created BEAM-6894:
----------------------------------------

             Summary: ExternalTransform.expand() does not create the proper AppliedPTransform sub-graph
                 Key: BEAM-6894
                 URL: https://issues.apache.org/jira/browse/BEAM-6894
             Project: Beam
          Issue Type: Bug
          Components: sdk-py-core
            Reporter: Chamikara Jayalath


'ExternalTransform.expand()' can be used to expand a remote transform and build the correct runner-api subgraph for that transform. However currently we do not modify the AppliedPTransform sub-graph correctly during this process. Relevant code location here.

[https://github.com/apache/beam/blob/master/sdks/python/apache_beam/transforms/external.py#L135]

 

Without this, DataflowRunner that relies in this object graph (not just the runner API proto) to build the job submission request to Dataflow service cannot construct this request properly.
