Question

我尝试在Windows 10系列上将Hadoop与Docker Toolbox一起使用。因此，我按照以下设置进行操作：https://linoxide.com/cluster/setup-single-node-hadoop-cluster-docker/

下载图像->确定。
运行容器->确定。

$ docker run -it sequenceiq/hadoop-docker:2.7.1 /etc/bootstrap.sh -bash/
Starting sshd:                                             [  OK  ]
18/11/16 10:38:22 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

localhost: starting nodemanager, logging to /usr/local/hadoop/logs/yarn-root-nodemanager-c13feb9767ac.out

运行jps命令->确定。

bash-4.1# jps
119 NameNode
535 ResourceManager
200 DataNode
656 Jps
319 SecondaryNameNode
620 NodeManager

获取IP地址->确定。

bash-4.1# ifconfig
...
inet addr:172.17.0.2
...

转到浏览器（Google Chrome v70）-> KO。

使用的地址：172.17.0.2:50070

错误：

此网站无法访问172.17.0.2花了很长时间才回答。

您能帮我修复它吗？如果您需要更多信息，请问我。

谢谢。

更新1：

docker ps结果：

c13feb9767ac      sequenceiq/hadoop-docker:2.7.1   "/etc/bootstrap.sh -…"   20 minutes ago      Up 20 minutes       2122/tcp, 8030-8033/tcp, 8040/tcp, 8042/tcp, 8088/tcp, 19888/tcp, 49707/tcp, 50010/tcp, 50020/tcp, 50070/tcp, 50075/tcp, 50090/tcp   xenodochial_euclid

更新2：

我在防火墙上打开了端口50070，但问题仍然存在。

Answer 1

至少，您需要暴露端口。

docker run -it -p 50070:50070 sequenceiq/hadoop-docker:2.7.1

然后，如果您想继续使用旧的Docker工具箱（该链接文章创建于2016年，在Docker for Windows出现之前），则无需使用ifconfig，而应使用{{1} }，而不是Windows

我个人使用Docker Compose

docker-machine ip

hadoop.env

Docker上的Hadoop无法访问站点
