RE: build failure - trying to build hadoop trunk checkout
Thanks for the replies all. I'll investigate changing my hostname and report back.

(Seems a bit hacky though - can someone explain using easy words why this happens in Kerberos?)

Never mind filing. I recalled that we debugged this issue long time back and cornered this down to problems with kerberos. See https://issues.apache.org/jira/browse/HADOOP-7988.

Given that, Tony, changing your hostname seems to be the only option.

Thanks,

file this as a JIRA against hadoop-common, though your machine's hostname looks suspiciously close to breaking the RFC-952 rules on hostnames

 Hi,

I'm following the steps at http://wiki.apache.org/hadoop/HowToContribute for building hadoop in preparation for submitting a patch.

I've checked out the trunk, and when I run "mvn test" from the top-level directory, I get the following error (snipped for clarity):

Results :

Failed tests:   testLocalHostNameForNullOrWild(org.apache.hadoop.security.TestSecurityUtil): expected:<hdfs/tonyb-[Precision-WorkS]tation-390@REALM> but was:<hdfs/tonyb-[precision-works]tation-390@REALM>

The test in question is:

@Test
  public void testLocalHostNameForNullOrWild() throws Exception {
    String local = SecurityUtil.getLocalHostName();
    assertEquals("hdfs/" + local + "@REALM",
                 SecurityUtil.getServerPrincipal("hdfs/_HOST@REALM", (String)null));
    assertEquals("hdfs/" + local + "@REALM",
                 SecurityUtil.getServerPrincipal("hdfs/_HOST@REALM", "0.0.0.0"));
  }

And my hostname is tonyb-Precision-WorkStation-390.

Any idea how I can get this test to pass?

Thanks,

Tony
