我已经安装了基于centos7的hadoop2.7.2，它是一个有3个从机的主设备。
问题是我只能通过访问 localhost:50070 在主机中。而且去看医生也不管用 master:50070 或者 192.168.199.139:50070 , 192.168.199.139 是主机的ip地址。
同时，奴隶们也不能参观 192.168.199.139:50070 .
我需要更多指定的配置来访问吗 50070 ?
跑 ifconfig 在母版中：

如果在/etc/hosts中用关联的ip更新主机名，那么只有您才能从任何计算机访问namenode。在hosts文件中添加如下内容
192.168.199.139 masterp、 所有机器中的主机应相同7xllpg7q2#
你应该检查参数
dfs.namenode.http-address在文件中hdfs-site.xml. 默认值0.0.0.0:50070允许从任何地方连接。但如果你有价值localhost:50070那么只允许从localhost进行连接。
