[jira] [Commented] (KAFKA-14648) Do not fail clients if bootstrap servers is not immediately resolvable

["Kirk True (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-14648?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17685418#comment-17685418 ] 

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.

> 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.
