-----------------------------------
Summary: SDK harnesses should be able to indicate panic in FnAPI
Key: BEAM-2947
URL: https://issues.apache.org/jira/browse/BEAM-2947
Project: Beam
Issue Type: Improvement
Components: beam-model
Reporter: Henning Rohde
Priority: Minor
If the SDK harness encounters a permanent problem (local file corruption or bad
staged files, say) it should be able to rely that information to the runner as
a "panic" message, say. Such conditions may also happen during the boot stage.
Using process/container exit codes would likely not work well, because that
information may not flow easily to the runner logic depending on how containers
are managed.
