> Key: FLINK-3570
> URL: https://issues.apache.org/jira/browse/FLINK-3570
> Project: Flink
> Issue Type: Improvement
> Components: Distributed Runtime
> Affects Versions: 1.0.0, 1.1.0
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Priority: Minor
>
> Currently, the {{ConnectionUtils.findAddressUsingStrategy}} method returns
> the first {{NetworkInterface}} whose address is not a loop back address, not
> a link local address and an {{Inet4Address}}. Before returning this address,
> it is retried to connect to the {{JobManager}} using the
> {{InetAddress.getLocalHost}} address a last time.
> The heuristic, if not choosing the {{InetAddress.getLocalHost}}, often makes
> no sense because it returns a random {{NetworkInterface}} address. It would
> be better to simply return the {{InetAddress.getLocalHost()}} instead.
