我的namenode和datanode启动正常，但执行start-dfs.sh命令时，出现错误，
每句中都报..Could not resolve hostname...!
连接方式是hostonly，hadoop2.6.0
[root@h1 ~]# cat /etc/hostname
192.168.1.101
[root@h1 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.101 h1
192.168.1.102 h2
192.168.1.103 h3
192.168.1.104 h4
192.168.1.105 h5
192.168.1.106 h6
192.168.1.107 h7
[root@h1 ~]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=h1
这是我自己的模拟搭建，多多包涵~
待大神解答n(*≧▽≦*)n
[root@h1 ~]# **start-dfs.sh**
