             Summary: LeaderTragicEventTest is flaky
                 Key: SOLR-18025
                 URL: https://issues.apache.org/jira/browse/SOLR-18025
             Project: Solr
          Issue Type: Improvement
          Components: Tests
            Reporter: Jan Høydahl


LeaderTragicEventTest shows significant flakiness in CI builds over the last 28 
days:

  - 42 flaky test occurrences (4% flaky rate)

  - 1,110 passed occurrences (96%)

  - Mean execution time: 8.0 seconds

 

This test is related to LUCENE-8692 where IndexWriter.getTragicException() may 
not reflect all corrupting exceptions. The test uses MockDirectoryWrapper's 
corruptFiles to introduce corruption and expects the leader to give up 
leadership, but this doesn't always happen reliably.

Multiple Jenkins build failures observed across Solr-Test-10.x, Solr-Test-10.0, 
and Solr-Test-main.

Should we consider marking as @BadApple annotation?
