-------------------------------
Summary: Shading model-pipeline / model-fn-execution /
model-job-management produces corrupted classes
Key: BEAM-4484
URL: https://issues.apache.org/jira/browse/BEAM-4484
Project: Beam
Issue Type: Bug
Components: runner-direct
Reporter: Luke Cwik
Assignee: Luke Cwik
During investigation for test failures on
[https://github.com/apache/beam/pull/5445,] I discovered that the the post
shaded beam-model-pipeline proto filedescriptors were corrupted. It turns out
that during the shading process, an over eager string replacement inside a
class is corrupting an internal field, in this case it modifies the RunnerApi
file descriptor storing
{code:java}
org.apache.beam.model.pipeline.v1.AccumulationMode.Enum{code}
and changing it to
{code:java}
org.apache.beam.repackaged.beam_runners_direct_java.model.pipeline.v1.AccumulationMode.Enum{code}
This problem exists because the proto package name and the java package name
collide and use org.apache.beam.model.pipeline.v1.
