我打不开 namenode:50070 然而， namenode:50030 很好用。

我在virtualbox上设置了一个2节点集群。主机操作系统是Windows7，我有两个客人都是ubuntu。一从一主。
主人 /etc/hosts :

127.0.0.1   localhost
192.168.1.124   namenode
192.168.1.125   slave1

主人 /etc/network/interfaces :

auto lo
iface lo inet loopback 

auto eth2
iface eth2 inet static
address 192.168.1.124
netmask 255.255.255.0

奴隶 /etc/hosts :

127.0.0.1   localhost
192.168.1.124   namenode
192.168.1.125   slave1

奴隶 /etc/network/interfaces :

auto lo
iface lo inet loopback

auto eth3
iface eth3 inet static
address 192.168.1.125
netmask 255.255.255.0

为什么我不能打开 50070 ?
当我这么做的时候 netstat -ar 编号：

Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
169.254.0.0     0.0.0.0         255.255.0.0     U         0 0          0 eth2
192.168.1.0     0.0.0.0         255.255.255.0   U         0 0          0 eth2

这个输出表明我的节点确实启动了。不是吗？
