我有一个cdh4.3一体机的虚拟机和运行，我试图安装一个hadoop客户端远程。我注意到，在不更改任何默认设置的情况下，我的hadoop集群正在侦听 127.0.0.1:8020 .

[cloudera@localhost ~]$ netstat -lent | grep 8020
tcp        0      0 127.0.0.1:8020              0.0.0.0:*                   LISTEN      492        100202 

[cloudera@localhost ~]$ telnet ${all-in-one vm external IP} 8020
Trying ${all-in-one vm external IP}...
telnet: connect to address ${all-in-one vm external IP} Connection refused
[cloudera@localhost ~]$ telnet 127.0.0.1 8020
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'

我的远程机器有所有的配置( core-site.xml, hdfs-site.xml )指向 ${all-in-one vm external IP} . 当我从远程客户端运行一些东西时，我得到：

└ $ ./bin/hdfs --config /home/${myself}/hadoop-2.0.0-cdh4.3.0/etc/hadoop dfs -ls
13/10/27 05:27:53 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
ls: Call From ubuntu/127.0.1.1 to ${all-in-one vm external IP}:8020 failed on connection exception: java.net.ConnectException: Connection refused; For more details see:  http://wiki.apache.org/hadoop/ConnectionRefused

我更改了hadoop一体机虚拟机： core-site.xml and hdfs-site.xml 低于 /etc/hadoop/conf 发件人： localhost.localdomain -> ${all-in-one vm external IP}, 但在重启hdfs之后，它仍然侦听localhost 8020。有什么想法吗？如何让它在8020上而不是本地主机上侦听${external ip}。
