> When the admin client closes, it should ensure that any pending futures get cancelled. For the most part it does so, but from glancing at the code, it seems possible that some calls which haven't been sent may be left hanging after shutdown. In particular, this collection is not cleaned on shutdown: https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/clients/admin/KafkaAdminClient.java#L961.
