I don't see the FileChangeWatcherTest.testCallbackWorksOnFileDeleted on latest flaky build: https://ci-hadoop.apache.org/blue/organizations/jenkins/ZooKeeper-Find-Flaky-Tests/detail/ZooKeeper-Find-Flaky-Tests/339/pipeline It was actually flaky, but should have been already fixed: ZOOKEEPER-3219
However, the other ones, on branch 3.5, looks flaky (so probably also are on master): ZooKeeperServerMainTest.testReadOnlySnapshotDir ZooKeeperServerMainTest.testReadOnlyTxnLogDir You can try to re-run the failed tests individually: mvn -Dtest=FileChangeWatcherTest -DfailIfNoTests=false test If they pass you can try to re-run the whole tests again. We do have some flaky tests, and fixes are always welcomed. Please check first if there's already a jira ticket for it: https://issues.apache.org/jira/browse/ZOOKEEPER-3042?jql=text%20~%20%22flaky%22 >From the logs it looks like it's an issue of the multi thread test runs, sometimes ZK instances get stuck (it's a valid question why we have ZK instances fired up in unit tests). - Norbert On Mon, Aug 2, 2021 at 11:20 AM dinesh singla <tycon.sin...@gmail.com> wrote: > Hi Norbert, > > I am currently at master branch and when i run maven clean and install here > I am getting an error on a test case and the error is > > > > > > > > > > > > > > > *[ERROR] Failures: [ERROR] > FileChangeWatcherTest.testCallbackWorksOnFileDeleted:210 expected: > <ENTRY_DELETE> but was: <ENTRY_MODIFY>[ERROR] > NettyServerCnxnFactoryTest.testOutstandingHandshakeLimit:155 Only 0 out of > 9 connections created![ERROR] > ZooKeeperServerMainTest.testReadOnlySnapshotDir:254 waiting for server > being up ==> expected: <false> but was: <true>[ERROR] > ZooKeeperServerMainTest.testReadOnlyTxnLogDir:293 waiting for server being > up ==> expected: <false> but was: <true>[ERROR] > > LearnerMetricsTest.testLearnerMetricsTest:101->waitForMetric:118->ZKTestCase.waitFor:110 > unable to match on metric: learner_proposal_received_count[ERROR] > QuorumPeerMainTest.testFailedTxnAsPartOfQuorumLoss:792 create /zk2 should > have failed[ERROR] QuorumPeerMainTest.testLeaderOutOfView:916 expected: > <LOOKING> but was: <FOLLOWING>[ERROR] > QuorumSSLTest.testCertificateRevocationList:758 expected: <true> but was: > <false>[ERROR] > > QuorumSSLTest.testHostnameVerificationWithInvalidIpAddressAndValidHostname:657->testHostnameVerification:722 > expected: <true> but was: <false>[ERROR] QuorumSSLTest.testOCSP:829 > expected: <true> but was: <false>[ERROR] > ReconfigBackupTest.testVersionOfDynamicFilename:319 expected: <true> but > was: <false>[ERROR] StatResetCommandTest.testStatResetWithFollower:82 > expected: <Server stats reset.> but was: <Server stats reset.* > > > > Can you please tell me if I am doing something wrong here or if this needs > to be fixed?
