{code} Stacktrace java.lang.AssertionError: Condition not met within timeout 30000. waiting for final values at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:26) at org.apache.kafka.test.TestUtils.lambda$waitForCondition$5(TestUtils.java:381) at org.apache.kafka.test.TestUtils.retryOnExceptionWithTimeout(TestUtils.java:429) at org.apache.kafka.test.TestUtils.retryOnExceptionWithTimeout(TestUtils.java:397) at org.apache.kafka.test.TestUtils.waitForCondition(TestUtils.java:380) at org.apache.kafka.test.TestUtils.waitForCondition(TestUtils.java:368) at org.apache.kafka.streams.integration.GlobalKTableEOSIntegrationTest.shouldKStreamGlobalKTableLeftJoin(GlobalKTableEOSIntegrationTest.java:178) {code} I looked at the below examples: https://builds.apache.org/job/kafka-pr-jdk14-scala2.13/149/testReport/junit/org.apache.kafka.streams.integration/GlobalKTableEOSIntegrationTest/shouldKStreamGlobalKTableLeftJoin_exactly_once_beta_/ https://builds.apache.org/job/kafka-pr-jdk11-scala2.13/6017/testReport/junit/org.apache.kafka.streams.integration/EosIntegrationTest/shouldNotViolateEosIfOneTaskFailsWithState_exactly_once_beta__2/ https://builds.apache.org/job/kafka-pr-jdk11-scala2.13/6017/testReport/junit/org.apache.kafka.streams.integration/GlobalKTableEOSIntegrationTest/shouldKStreamGlobalKTableLeftJoin_exactly_once_beta__2/ And also reproduced the flakiness locally after about 180 runs, and the failed one did not have any obvious different traces compared with the successful ones. -- This message was sent by Atlassian Jira (v8.3.4#803005)
