             Summary: Hosts names resolution takes place even if all nodes are configured via ip addresses
                 Key: IGNITE-12873
                 URL: https://issues.apache.org/jira/browse/IGNITE-12873
             Project: Ignite
          Issue Type: Improvement
            Reporter: Kirill Tkalenko
            Assignee: Kirill Tkalenko
             Fix For: 2.9


We got a problem: When connection with DNS was lost transactions processing hanged up. This happened because IgniteUtils.toSocketAddresses resolves hostName even if all nodes are configured via ip-addresses.

Solution:
- Do not save hostname in node attributes, If localHost IP is set in the configuration
- Add JVM option for enabling "old" behaviour.
