Summary: Zookeeper test case testCommunicationFailureResolve_KillRandom frequently fails in GridAbstractTest.waitForTopology Key: IGNITE-10988 URL: https://issues.apache.org/jira/browse/IGNITE-10988 Project: Ignite Issue Type: Bug Affects Versions: 2.7 Reporter: Oleg Ignatenko Zookeeper test case testCommunicationFailureResolve_KillRandom frequently fails in GridAbstractTest.waitForTopology. Teamcity test history in master currently shows "Test runs: 625 total / 251 failures" ([link|https://ci.ignite.apache.org/project.html?projectId=IgniteTests24Java8&testNameId=-3849782382784091413&tab=testDetails). Need to find out why is that and whether test case can be improved and made more reliable. Typical failure message looks as follows: {noformat} [2019-01-18 06:57:23,489][ERROR][main][root] Test failed. junit.framework.AssertionFailedError at junit.framework.Assert.fail(Assert.java:55) at junit.framework.Assert.assertTrue(Assert.java:22) at junit.framework.Assert.assertTrue(Assert.java:31) at org.apache.ignite.testframework.junits.GridAbstractTest.waitForTopology(GridAbstractTest.java:2294) at org.apache.ignite.spi.discovery.zk.internal.ZookeeperDiscoverySpiTest.waitForTopology(ZookeeperDiscoverySpiTest.java:5103) at org.apache.ignite.spi.discovery.zk.internal.ZookeeperDiscoverySpiTest.testCommunicationFailureResolve_KillRandom(ZookeeperDiscoverySpiTest.java:3145) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:47) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:44) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.apache.ignite.testframework.junits.GridAbstractTest$6.run(GridAbstractTest.java:2088) at java.lang.Thread.run(Thread.java:748){noformat} ---- Side note per IGNITE-10777 this test case has moved to another class, from {{ZookeeperDiscoverySpiTest}} to {{ZookeeperDiscoverySpiTest5}} but that didn't change anything: it still fails frequently and failure message is the same, with the only difference in the new test class name. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
