             Summary: Many tools try to connect to embedded ZK on IPV6
                 Key: SOLR-16150
                 URL: https://issues.apache.org/jira/browse/SOLR-16150
             Project: Solr
          Issue Type: Test
            Reporter: Mike Drob


We have a lot of places internally where we try to connect to "localhost" and end up hitting the ipv6 interface for whatever reason. Is this an OS issue? A VPN issue?

Regardless, the embedded ZK isn't listening on ipv6, so we fail and retry (sometimes multiple times). Each retry adds a second to our tests, but should be easy to give a more specific address to connect to.
