[jira] [Created] (KAFKA-9313) Set default for client.dns.lookup to use_all_dns_ips

Yeva Byzek created KAFKA-9313:
---------------------------------

             Summary: Set default for client.dns.lookup to use_all_dns_ips
                 Key: KAFKA-9313
                 URL: https://issues.apache.org/jira/browse/KAFKA-9313
             Project: Kafka
          Issue Type: Improvement
          Components: clients
            Reporter: Yeva Byzek


The default behavior of client.dns.lookup is not use_all_dns_ips, which means if there are multiple IP addresses and the first one fails, the connection will fail.

 

It is desirable to set the default to be client.dns.lookup=use_all_dns_ips for two reasons:
 # reduce connection failure rates by 
 # users are often surprised that this is not already the default
