I'm getting a few random test errors when building the 1.2.0 source release. The failures seem to be completely random. I have built many times per the steps below and most times everything is ok but every now and then one of the tests fails. I can't reproduce any of them in Maven or Eclipse.
Here are my steps: 1. Provision a new Ubuntu 16 VM (t2.small on EC2). 2. wget https://dist.apache.org/repos/dist/dev/nifi/nifi-1.2.0/nifi- 1.2.0-source-release.zip 3. unzip nifi-1.2.0-source-release.zip 4. cd nifi-1.2.0-source-release 5. mvn clean install -Pcontrib-check Other details: Apache Maven 3.3.9 openjdk version "1.8.0_121" Ubuntu 16.04.2 LTS The failing tests (Note that all 3 of these failed separately across different builds and not in any single build): Running org.apache.nifi.controller.scheduling.TestStandardProcessScheduler Tests run: 9, Failures: 1, Errors: 0, Skipped: 1, Time elapsed: 16.091 sec <<< FAILURE! - in org.apache.nifi.controller.scheduling.TestStandardProcessScheduler validateServiceEnablementLogicHappensOnlyOnce(org.apache.nifi.controller.scheduling.TestStandardProcessScheduler) Time elapsed: 0.824 sec <<< FAILURE! java.lang.AssertionError: expected:<1> but was:<0> at org.junit.Assert.fail(Assert.java:88) at org.junit.Assert.failNotEquals(Assert.java:834) at org.junit.Assert.assertEquals(Assert.java:645) at org.junit.Assert.assertEquals(Assert.java:631) at org.apache.nifi.controller.scheduling.TestStandardProcessScheduler.validateServiceEnablementLogicHappensOnlyOnce(TestStandardProcessScheduler.java:266) Running org.apache.nifi.controller.service.TestStandardControllerServiceProvider Tests run: 8, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 125.657 sec <<< FAILURE! - in org.apache.nifi.controller.service.TestStandardControllerServiceProvider testConcurrencyWithEnablingReferencingServicesGraph(org.apache.nifi.controller.service.TestStandardControllerServiceProvider) Time elapsed: 120.098 sec <<< ERROR! org.junit.runners.model.TestTimedOutException: test timed out after 120000 milliseconds at java.util.HashMap.putVal(HashMap.java:630) at java.util.HashMap.put(HashMap.java:611) at java.util.HashSet.add(HashSet.java:219) at org.apache.commons.lang3.ClassUtils.getAllInterfaces(ClassUtils.java:470) at org.apache.commons.lang3.ClassUtils.getAllInterfaces(ClassUtils.java:471) at org.apache.commons.lang3.ClassUtils.getAllInterfaces(ClassUtils.java:454) at org.apache.nifi.controller.service.StandardControllerServiceProvider.createControllerService(StandardControllerServiceProvider.java:126) at org.apache.nifi.controller.service.TestStandardControllerServiceProvider.testEnableReferencingServicesGraph(TestStandardControllerServiceProvider.java:214) at org.apache.nifi.controller.service.TestStandardControllerServiceProvider.testConcurrencyWithEnablingReferencingServicesGraph(TestStandardControllerServiceProvider.java:188) Running org.apache.nifi.controller.scheduling.TestProcessorLifecycle Tests run: 16, Failures: 1, Errors: 0, Skipped: 2, Time elapsed: 47.215 sec <<< FAILURE! - in org.apache.nifi.controller.scheduling.TestProcessorLifecycle validateProcessScheduledAfterAdministrativeDelayDueToTheOnScheduledException(org.apache.nifi.controller.scheduling.TestProcessorLifecycle) Time elapsed: 3.981 sec <<< FAILURE! java.lang.AssertionError: null at org.junit.Assert.fail(Assert.java:86) at org.junit.Assert.assertTrue(Assert.java:41) at org.junit.Assert.assertTrue(Assert.java:52) at org.apache.nifi.controller.scheduling.TestProcessorLifecycle.validateProcessScheduledAfterAdministrativeDelayDueToTheOnScheduledException(TestProcessorLifecycle.java:373) Any ideas? Could an EC2 t2.small (2 GB RAM) be insufficient for the build? Thanks, Jeff
