Guozhang Wang commented on KAFKA-6137: -------------------------------------- It sounds like an environment issue to me as the following condition is not expected to pass: {code} if (!taskDir.exists() && !taskDir.mkdir()) { throw new ProcessorStateException( String.format("task directory [%s] doesn't exist and couldn't be created", taskDir.getPath())); } {code} I'd suggest leaving this ticket open for some time and see if we observe similar issues again. If not we can close as cannot reproduce. > RestoreIntegrationTest sometimes fails with assertion error > ----------------------------------------------------------- > > Key: KAFKA-6137 > URL: https://issues.apache.org/jira/browse/KAFKA-6137 > Project: Kafka > Issue Type: Test > Components: streams, unit tests > Reporter: Ted Yu > Priority: Minor > Labels: flaky-test > > From https://builds.apache.org/job/kafka-1.0-jdk7/62 : > {code} > org.apache.kafka.streams.integration.RestoreIntegrationTest > > shouldSuccessfullyStartWhenLoggingDisabled FAILED > java.lang.AssertionError > 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.kafka.streams.integration.RestoreIntegrationTest.shouldSuccessfullyStartWhenLoggingDisabled(RestoreIntegrationTest.java:195) > {code} -- This message was sent by Atlassian JIRA (v6.4.14#64029)
