----------------------------------------
Summary: Intermittent failure in interpreter-test-non-core (11)
job of core GitHub Actions workflow
Key: ZEPPELIN-6194
URL: https://issues.apache.org/jira/browse/ZEPPELIN-6194
Project: Zeppelin
Issue Type: Task
Reporter: Gyeongtae Park
Assignee: Gyeongtae Park
Fix For: 1.0.0, 0.13.0
*Problem Summary:*
The {{interpreter-test-non-core (11)}} job within the {{core}} GitHub Actions
workflow occasionally fails during the Conda environment setup phase. These
failures are non-deterministic (flaky) and do not correlate with specific code
changes, indicating an environment-related root cause.
*Details:*
The failure typically occurs when resolving dependencies using Conda, with the
following error observed:
{code:java}
python: /croot/libsolv-suite.../rules.c:261: solver_addrule: Assertion `!p2 &&
d > 0' failed. {code}
This assertion failure is triggered by Conda's dependency resolver (libsolv)
when it encounters unresolved or conflicting constraints.
Previously, the workflow used channel-priority: true, which corresponds to
flexible priority mode. This allowed mixing packages from both conda-forge and
defaults, potentially leading to dependency conflicts.
