--------------------------------------
Summary: Create an in-memory DNS server for ClientUtilsTest and
ClusterConnectionStatesTest
Key: KAFKA-10496
URL: https://issues.apache.org/jira/browse/KAFKA-10496
Project: Kafka
Issue Type: Improvement
Reporter: Justine Olshan
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.
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.
