Is it a bug?

[Skater <xq...@163.com>]

  /** @deprecated */
  public DistributedFileSystem(InetSocketAddress namenode,
    Configuration conf) throws IOException {
    initialize(URI.create("hdfs://"+
                          namenode.getHostName()+":"+
                          namenode.getPort()),
                          conf);
  }

  /** @deprecated */
  public String getName() { return uri.getAuthority(); }

  public URI getUri() { return uri; }

  public void initialize(URI uri, Configuration conf) throws IOException {
    setConf(conf);
    String host = uri.getHost();
    int port = uri.getPort();
    System.out.println(host);
    System.out.println(port);
    System.out.println(conf);

    //here the host=null and port = -1, after debugging.
    this.dfs = new DFSClient(new InetSocketAddress(host,port), conf);
    this.uri = URI.create("hdfs://"+host+":"+port);
  }


SO I cannot start the name node.
COuld you help me?

I tried a lot of way to let the 0.16.2 start, but I failed at here.
Is there need some special configuration?

My configuraions are:
<configuration>
<property>
  <name>hadoop.tmp.dir</name>
  <value>/tmp/hadoop-${user.name}</value>
</property>
<property>
  <name>fs.default.name</name>
  <value>localhost:9000</value>
</property>
<property>
  <name>mapred.job.tracker</name>
  <value>localhost:54311</value>
</property>
<property>
  <name>dfs.replication</name>
  <value>8</value>
</property>
<property>
  <name>mapred.child.java.opts</name>
  <value>-Xmx512m</value>
</property>
</configuration>
