---------------------------------
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
