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

             Summary: Background exception was not retry-able or retry gave up
                 Key: CURATOR-649
                 URL: https://issues.apache.org/jira/browse/CURATOR-649
             Project: Apache Curator
          Issue Type: Bug
          Components: Client
    Affects Versions: 5.2.0
            Reporter: Sergey Nuyanzin


This is is probably a kind of reopen of CURATOR-538
the case is we have 3 flink-nodes which under the hood using curator.
Then just add one node and remove another one. 
After that some nodes start having NPE.
We've got same issue and trace is very close it fails with NPE trying get Address
the only difference is that it is trying to get Address at {{org.apache.curator.utils.Compatibility#getHostAddress}}
at line 
{noformat}
return (address != null) ? address.getAddress().getHostAddress() : "unknown";
{noformat}
We do not use telepresence mentioned in comments
