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>

{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.
