kezhuw opened a new pull request, #2067: URL: https://github.com/apache/zookeeper/pull/2067
All tests are refactored to fail before #1988 and resist more than 100 runs locally without failure after #1988. ## Context I saw several failed ci actions due to flaky [`CheckTest::testCluster`](https://github.com/apache/zookeeper/blob/b31f776471fef79ab161f416d58367bdffaf37a9/zookeeper-server/src/test/java/org/apache/zookeeper/test/CheckTest.java#L94) after #1988 merged: 1. https://github.com/apache/zookeeper/actions/runs/6204227199/job/16879362878#step:7:767 2. https://github.com/apache/zookeeper/actions/runs/6211501232/job/16860755400#step:7:770 ``` org.opentest4j.AssertionFailedError: Unable to connect to server at org.apache.zookeeper.test.ClientBase.createClient(ClientBase.java:215) at org.apache.zookeeper.test.ClientBase.createClient(ClientBase.java:201) at org.apache.zookeeper.test.CheckTest.testCluster(CheckTest.java:107) ``` In investigation, I constructed a commit https://github.com/kezhuw/zookeeper/commit/e452ff954b2dc789a839472634b69b2569c2d2b3 in [branch in my fork](https://github.com/kezhuw/zookeeper/commits/quorum-base-double-leader) basing on code before #1988. The commit is extracted from above flaky test. It still could not resist about 20 runs. So I think we are safe to go with this pr. * If it is a test problem, the test has been refactored and verified locally with enough runs. * If it is a production problem, then it is a possibly unrelated issue. ## TLDR: The log reveals potential double leading **I am still investigating, so I can be completely wrong!** I was thinking it is related to [Oracle Quorum](https://zookeeper.apache.org/doc/current/zookeeperOracleQuorums.html), but the test still fail after changing `withOracle` to `false` in `setUp`. `server3` is the old leader. ``` 2023-09-19 19:10:12,592 [myid:] - INFO [QuorumPeer[myid=3](plain=127.0.0.1:11267)(secure=disabled):o.a.z.s.q.Leader@591] - LEADING - LEADER ELECTION TOOK - 289 MS ``` <details> <summary>In election after `server3` started, both `server1` and `server2` proposed `server2` as new leader.</summary> ``` 2023-09-19 19:10:14,072 [myid:] - INFO [QuorumPeer[myid=2](plain=127.0.0.1:11266)(secure=disabled):o.a.z.s.q.Follower@286] - shutdown Follower 2023-09-19 19:10:14,072 [myid:] - INFO [QuorumPeer[myid=2](plain=127.0.0.1:11266)(secure=disabled):o.a.z.s.q.QuorumPeer@920] - Peer state changed: looking 2023-09-19 19:10:14,072 [myid:] - WARN [QuorumPeer[myid=2](plain=127.0.0.1:11266)(secure=disabled):o.a.z.s.q.QuorumPeer@1602] - PeerState set to LOOKING 2023-09-19 19:10:14,072 [myid:] - INFO [QuorumPeer[myid=2](plain=127.0.0.1:11266)(secure=disabled):o.a.z.s.q.QuorumPeer@1471] - LOOKING 2023-09-19 19:10:14,073 [myid:] - INFO [QuorumPeer[myid=2](plain=127.0.0.1:11266)(secure=disabled):o.a.z.s.q.FastLeaderElection@946] - New election.
