[jira] [Created] (MAPREDUCE-5647) no property for changing ShuffleHandler binding host

subes created MAPREDUCE-5647:
--------------------------------

             Summary: no property for changing ShuffleHandler binding host
                 Key: MAPREDUCE-5647
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5647
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
    Affects Versions: 2.2.0
            Reporter: subes


org.apache.hadoop.mapred.ShuffleHandler has a property "mapreduce.shuffle.port" with the default value "13562", though there is no "mapreduce.shuffle.host".

Thus ShuffleHandler always binds to 0.0.0.0 and it is thus impossible to make hadoop completely bind to localhost if desired. This setting is in contrast available for all other port bindings.
