-----------------------------------
Resolution: Fixed
Reviewer: Rajini Sivaram
> Kafka clients should try to use multiple DNS resolved IP addresses if the
> first one fails
> -----------------------------------------------------------------------------------------
>
> Key: KAFKA-6863
> URL: https://issues.apache.org/jira/browse/KAFKA-6863
> Project: Kafka
> Issue Type: Improvement
> Components: clients
> Affects Versions: 1.0.0, 1.1.0
> Reporter: Edoardo Comar
> Assignee: Edoardo Comar
> Priority: Major
> Fix For: 2.1.0
>
>
> Currently Kafka clients resolve a symbolic hostname using
> {{new InetSocketAddress(String hostname, int port)}}
> which only picks one IP address even if the DNS has multiple records for the
> hostname, as it calls
> {{InetAddress.getAllByName(host)[0]}}
> For some environments where the hostnames are mapped by the DNS to multiple
> IPs, e.g. in clouds where the IPs point to the external load balancers, it
> would be preferable that the client, on failing to connect to one of the IPs,
> would try the other ones before giving up the connection.
