Dmitry Adarov updated NIFI-15698:
---------------------------------
Affects Version/s: 2.8.0
> NiFi Python bridge startup hang
> -------------------------------
>
> Key: NIFI-15698
> URL: https://issues.apache.org/jira/browse/NIFI-15698
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 2.6.0, 2.8.0
> Environment: Docker, Docker image (apache/nifi:2.6.0)
> Reporter: Dmitry Adarov
> Priority: Major
>
> NiFi can hang during startup when loading a persisted flow containing many
> Python processors. In the failing case, the process remains alive, but
> startup stalls during Python processor initialization and does not reach the
> normal Started Server / Started Application completion markers.
> This reproduces on the official apache/nifi:2.6.0 image using the container’s
> default bundled Python 3.11.x, a synthetic Python extension NAR, and a
> generated persisted flow.json.gz containing many no-op Python processor
> instances. The issue is nondeterministic: it may not reproduce on the first
> attempt, but repeated restarts of the same container with the same persisted
> flow can trigger the stalled startup.
> In the failing state, logs stop progressing during Python processor creation,
> while Java thread dumps show blocking in the Python bridge path around
> NiFiPythonGateway and StandardPythonBridge.createProcessor(...).
> How to reproduce issue: [https://github.com/distroitt/nifi-bug]
