changed

                 Key: HBASE-3886
                 URL: https://issues.apache.org/jira/browse/HBASE-3886
             Project: HBase
          Issue Type: Improvement
            Reporter: stack


This is an interesting one.  HServerInfo is deprecated in TRUNK and replaced effectively by
a new class ServerName.  Both equate instances of HSI or SN if the two instances have the
same hostname and port.  Well, thats well and good but what if we are getting signals from
a server whose IP has changed?  In this case, we'll see the server in its new location come
in but we'll treat it as though we'd seen it already, thought its IP had changed.  We don't
want this.

This facility is needed for rare case where a server is moved from one IP to another.
