[jira] [Created] (HADOOP-9099) NetUtils.normalizeHostName fails on domains where UnknownHost resolves to an IP address

Ivan Mitic created HADOOP-9099:
----------------------------------

             Summary: NetUtils.normalizeHostName fails on domains where UnknownHost resolves to an IP address
                 Key: HADOOP-9099
                 URL: https://issues.apache.org/jira/browse/HADOOP-9099
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 1-win
            Reporter: Ivan Mitic
            Assignee: Ivan Mitic


I just hit this failure. We should use some more unique string for "UnknownHost":

Testcase: testNormalizeHostName took 0.007 sec
	FAILED
expected:<[65.53.5.181]> but was:<[UnknownHost]>
junit.framework.AssertionFailedError: expected:<[65.53.5.181]> but was:<[UnknownHost]>
	at org.apache.hadoop.net.TestNetUtils.testNormalizeHostName(TestNetUtils.java:347)

Will post a patch in a bit.

------------------------------------------------

I understand the problem after looked at Ivan's patch - "UnknownHost" was resolved to an IP in your setting.

------------------------------------------

Personally I would've used something even more unlikely, such as "ThisIsNotARealHostName-ItJustCant", but I guess UnknownHost123 is not very likely to exist :).

+1 (non-binding).

Tsz Wo (Nicholas), SZE commented on HADOOP-9099:
------------------------------------------------

TestNetUtils in branch-1-win does not fail in my machine.  Is there any special setting in your machine/network?

BTW, I just have a quick check of the InetAddress source code (http://www.docjar.com/html/api/java/net/InetAddress.java.html).  It seems that it won't do any lookup if the input string is already an numerical IP address.  However, it is probably jdk dependent.
