Alejandro Abdelnur commented on MAPREDUCE-4163:
-----------------------------------------------

What is the rational of the following change in the TestNodeStatusUpdater?

{code}
-      try {
-        Assert.assertEquals(InetAddress.getLocalHost().getCanonicalHostName()
-            + ":12345", nodeId.toString());
-      } catch (UnknownHostException e) {
-        Assert.fail(e.getMessage());
-      }
+      // NOTE: this really should be checking against the config value
+      Assert.assertEquals("localhost:12345", nodeId.toString());
{code}

This is failing in systems where localhost is not the first hostname in /etc/hosts for the loopback (i.e. CentOS5 where the first hostname is localhost.localdomain). Before was working just fine.
