-----------------------------------
Summary: Integration test for async bootstrap resolution recovers
after initial DNS failure
Key: KAFKA-21337
URL: https://issues.apache.org/jira/browse/KAFKA-21337
Project: Kafka
Issue Type: Sub-task
Components: clients
Reporter: TengYao Chi
Assignee: TengYao Chi
Inject a custom HostResolver via KafkaAdminClient#createInternal(config,
metrics, hostResolver) that throws UnknownHostException at first, then switch
it to resolve successfully before the configured bootstrap.resolve.timeout.ms
budget expires.
Verify the admin client completes a real call (e.g. listTopics) against the
real broker once resolution succeeds.
IIUC, this could follow the current pattern as ConcurrentListOffsetsRequestTest
