Kirk True commented on KAFKA-14648:
-----------------------------------
Would a fix for this cover the case where
`ClientUtils.parseAndValidateAddresses` can't resolve any of the addresses in
the bootstrap servers set? We're seeing a case where there's a blip in DNS
resolution during the time of `KafkaAdminClient` construction and it is
unrecoverable.
> Do not fail clients if bootstrap servers is not immediately resolvable

> URL: https://issues.apache.org/jira/browse/KAFKA-14648
> Project: Kafka
> Issue Type: Bug
> Reporter: Jason Gustafson
> Priority: Major
>
> In dynamic environments, such as system tests, there is sometimes a delay
> between when a client is initialized and when the configured bootstrap
> servers become available in DNS. Currently clients will fail immediately if
> none of the bootstrap servers can resolve. It would be more convenient for
> these environments to provide a grace period to give more time for
> initialization.
