             Summary: Flaky test – org.apache.kafka.clients.ClientUtilsTest.testParseAndValidateAddressesWithReverseLookup() 
                 Key: KAFKA-16596
                 URL: https://issues.apache.org/jira/browse/KAFKA-16596
             Project: Kafka
          Issue Type: Test
            Reporter: Igor Soarez


org.apache.kafka.clients.ClientUtilsTest.testParseAndValidateAddressesWithReverseLookup() failed in the following way:

 
{code:java}
org.opentest4j.AssertionFailedError: Unexpected addresses [93.184.215.14, 2606:2800:21f:cb07:6820:80da:af6b:8b2c] ==> expected: <true> but was: <false>	at app//org.junit.jupiter.api.AssertionFailureBuilder.build(AssertionFailureBuilder.java:151)	at app//org.junit.jupiter.api.AssertionFailureBuilder.buildAndThrow(AssertionFailureBuilder.java:132)	at app//org.junit.jupiter.api.AssertTrue.failNotTrue(AssertTrue.java:63)	at app//org.junit.jupiter.api.AssertTrue.assertTrue(AssertTrue.java:36)	at app//org.junit.jupiter.api.Assertions.assertTrue(Assertions.java:214)	at app//org.apache.kafka.clients.ClientUtilsTest.testParseAndValidateAddressesWithReverseLookup(ClientUtilsTest.java:65) {code}
As a result of the following assertions:

 
{code:java}
// With lookup of example.com, either one or two addresses are expected depending on
// whether ipv4 and ipv6 are enabled
List<InetSocketAddress> validatedAddresses = checkWithLookup(asList("example.com:10000"));
assertTrue(validatedAddresses.size() >= 1, "Unexpected addresses " + validatedAddresses);
List<String> validatedHostNames = validatedAddresses.stream().map(InetSocketAddress::getHostName)
        .collect(Collectors.toList());
List<String> expectedHostNames = asList("93.184.216.34", "2606:2800:220:1:248:1893:25c8:1946"); {code}
It seems that the DNS result has changed for example.com.
