                 Key: HADOOP-5191
                 URL: https://issues.apache.org/jira/browse/HADOOP-5191
             Project: Hadoop Core
          Issue Type: Bug
          Components: dfs
    Affects Versions: 0.18.2
         Environment: AIX 6.1 or Solaris
            Reporter: Bill Habermaas
            Priority: Minor


After creation and startup of the hadoop namenode on AIX or Solaris, you will only be allowed
to connect to the namenode via hostname but not IP.

fs.default.name=hdfs://p520aix61.mydomain.com:9000
Hostname for box is p520aix and the IP is 10.120.16.68

If you use the following url, "hdfs://10.120.16.68", to connect to the namenode, the exception
that appears below occurs. You can only connect successfully if "hdfs://p520aix61.mydomain.com:9000"
is used. 

Exception in thread "Thread-0" java.lang.IllegalArgumentException: Wrong FS: hdfs://10.120.16.68:9000/testdata,
expected: hdfs://p520aix61.mydomain.com:9000
