[jira] [Updated] (KAFKA-10496) Create an in-memory DNS server for
ClientUtilsTest and ClusterConnectionStatesTest
[ https://issues.apache.org/jira/browse/KAFKA-10496?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Justine Olshan updated KAFKA-10496:
-----------------------------------
Description:
ClientUtilsTest and ClusterConnectionStatesTest currently use an external DNS to resolve the IP addresses for kafka.apache.org. Until recently there were only two IP4 addresses, but now there is a third.
At first the tests were changed to just check for multiple addresses. [https://github.com/apache/kafka/pull/9294]
However, these tests are pretty fragile when they rely on outside sources, so it would make sense to create an in-memory DNS. This is what netty does for similar tests.
