Nick Shanin created SOLR-18586:
----------------------------------
Summary: TestTlogReplica testKillLeader, testRecovery and
testOnlyLeaderIndexes fail repeatedly in the 10.1.0 RC3 smoke tests
Key: SOLR-18586
URL: https://issues.apache.org/jira/browse/SOLR-18586
Project: Solr
Issue Type: Test
Reporter: Nick Shanin
h2. What was seen
In five completed runs of the Solr 10.1.0 RC3 smoke tester (artifacts rev
{{749712b71940c9f96d824c533f32f5c56dcd3924}}, JDK 21.0.12.1, aarch64), the
build failed every time. {{TestTlogReplica.testKillLeader}} and
{{TestTlogReplica.testRecovery}} failed in all five runs and
{{testOnlyLeaderIndexes}} in four of the five, across different random seeds
(for example {{787C6229591C6F1E}}, {{8D8640B367EDAD08}}, {{5AB00AEB1AE2392}}).
h2. Caveat
All five runs were on one small ARM host (4 CPUs, 7 GB), so a host effect is
not yet separated from a code or test cause. The failures repeat across seeds
on that host; whether they reproduce elsewhere is part of what this ticket
tracks.
h2. Related RC3 smoke failures
RecoveryAfterSoftCommitTest is SOLR-18530 (fix in PR #5098) and
TestCoordinatorRole.testNRTRestart is SOLR-16630 (fix in PR #5106); neither fix
is in RC3. This ticket covers the TlogReplica methods, which have no fix yet.
