Subject [jira] [Created] (HADOOP-9657) NetUtils.wrapException to have special handling for 0.0.0.0 addresses and :0 ports

Steve Loughran created HADOOP-9657:
--------------------------------------

             Summary: NetUtils.wrapException to have special handling for 0.0.0.0 addresses
and :0 ports
                 Key: HADOOP-9657
                 URL: https://issues.apache.org/jira/browse/HADOOP-9657
             Project: Hadoop Common
          Issue Type: Improvement
          Components: net
            Reporter: Steve Loughran
            Priority: Minor


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
