TestNetUtils fails on Mac OS X
------------------------------

                 Key: HADOOP-6747
                 URL: https://issues.apache.org/jira/browse/HADOOP-6747
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 0.22.0
         Environment: Mac OS 10.5.8 (Leopard)
            Reporter: Luke Lu
             Fix For: 0.22.0


TestNetUtils fails consistently after HADOOP-6722 on Mac OS X Leopard 10.5.8:

{{
------------- Standard Error -----------------
local address: /127.0.0.1
local port: 64991
------------- ---------------- ---------------

Testcase: testAvoidLoopbackTcpSockets took 0.421 sec
        Caused an ERROR

        at org.apache.hadoop.net.TestNetUtils.testAvoidLoopbackTcpSockets(TestNetUtils.java:46)
}}

Although TCP spec seems to allow it, at least one implementation disallows this corner case.
