-----------------------------------------
Summary: ShardSplitTest 100% failures on main branch
Key: SOLR-17360
URL: https://issues.apache.org/jira/browse/SOLR-17360
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Chris M. Hostetter
ShardSplitTest is a nightly only testclass that has 4 test methods which have
recently been failing 100% of the time in jenkins, regardless of seed...
* testSplitMixedReplicaTypes
* testSplitStaticIndexReplicationLink
* testSplitStaticIndexReplication
* testSplitMixedReplicaTypesLink
...but AFAICT these failures are not new. IIUC this test has been failing on
100% of – the _MAIN_ branch – jenkins builds since ~ Oct/Nov {*}2023{*}!
(I believe the historical graphs since then just look "sporadic" because it's a
nightly only test so run's very infrequently and was still (mostly) passing on
the 9x branch)
----
It's trivial to see these failures locally, regardless of seed; or whether you
run a single test method, or multiple test methods.
Example...
{noformat}
git clean -fd && ./gradlew -p solr/core test -Ptests.nightly=true --tests
ShardSplitTest.testSplitMixedReplicaTypes{noformat}
The failures are all fairly non-sopecific...

...with no errors in the logs indicating when/what might be going wrong.
