在VM上设置双节点Hadoop集群

Question

我无法打开namenode:50070，但是namenode:50030工作正常。

我在VirtualBox上设置了一个2节点集群。主机操作系统是Windows 7，我有2位客人都是ubuntu。 1个奴隶和1个主人。

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

为什么我无法打开50070？

当我做netstat -ar n：

时

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

此输出显示我的节点确实已启动。不是吗？

Answer 1

您的群集看起来有些问题。您的Web控制台显示zero个节点。确保您的Hadoop守护进程正常运行。你能够正确启动它们吗？使用JPS检查守护进程是否正常运行。
