> 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
