跟课程安装HADOOP集群时,怎么也打不开HADOOP网页,看不到集群信息,最后发现是课程有删除 /etc/hosts路径下的以下两行:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
粘贴回来后,
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.*.* hadoop101
192.168.*.* hadoop102
正常登录。
