我有一个 CDH4.3 一体式 vm 启动并运行,我正在尝试远程安装一个 hadoop 客户端。我注意到,在不更改任何默认设置的情况下,我的 hadoop 集群正在监听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 '^]'
我的远程机器的所有配置(core-site.xml, hdfs-site.xml
)都指向${all-in-one vm external IP}
. 当我从远程客户端运行某些东西时,我得到了这个:
└ $ ./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 ${all-in-one vm external IP}:8020 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused
我改变了我的hadoop all-in-one vm:
core-site.xml and hdfs-site.xml
under /etc/hadoop/conf
from: localhost.localdomain
->${all-in-one vm external IP},
但是在重新启动hdfs后,它仍然监听localhost 8020。有什么想法吗?如何让它在 8020 而不是 localhost 上收听 ${external IP}。
