> 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
