    Description

      when an exception is wrapped, it may look like 0.0.0.0:0 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused

      We should recognise all zero ip addresses and 0 ports and flag them as "your configuration of the endpoint is wrong", as it is clearly the case
