Guozhang Wang created KAFKA-3926:
------------------------------------

             Summary: Transient failures in org.apache.kafka.streams.integration.RegexSourceIntegrationTest
                 Key: KAFKA-3926
                 URL: https://issues.apache.org/jira/browse/KAFKA-3926
             Project: Kafka
          Issue Type: Sub-task
          Components: streams, unit tests
            Reporter: Guozhang Wang


{code}
org.apache.kafka.streams.integration.RegexSourceIntegrationTest > testRegexMatchesTopicsAWhenDeleted
FAILED
    java.lang.AssertionError: 
    Expected: <[TEST-TOPIC-A, TEST-TOPIC-B]>
         but: was <[TEST-TOPIC-A]>
        at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:20)
        at org.junit.Assert.assertThat(Assert.java:956)

        at org.apache.kafka.streams.integration.RegexSourceIntegrationTest.testRegexMatchesTopicsAWhenDeleted(RegexSourceIntegrationTest.java:211)
{code}

I think it is due to the fact that some times the rebalance takes much longer than the specified
60 seconds.

One example: https://builds.apache.org/job/kafka-trunk-jdk8/730/consoleFull
