docker - 使用 Docker 上的 Hadoop 无法访问站点

Question

我尝试在 Windows 10 系列上使用 Hadoop 和 Docker Toolbox。所以我遵循了这个设置:https://linoxide.com/cluster/setup-single-node-hadoop-cluster-docker/

1. 下载图片 --> 确定。
2. 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 applicableStarting namenodes on [c13feb9767ac]c13feb9767ac: starting namenode, logging to /usr/local/hadoop/logs/hadoop-root-namenode-c13feb9767ac.outlocalhost: starting datanode, logging to /usr/local/hadoop/logs/hadoop-root- datanode-c13feb9767ac.outStarting secondary namenodes [0.0.0.0]0.0.0.0: starting secondarynamenode, logging to /usr/local/hadoop/logs/hadoop-root-secondarynamenode-c13feb9767ac.out18/11/16 10:40:34 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicablestarting yarn daemonsstarting resourcemanager, logging to /usr/local/hadoop/logs/yarn--resourcemanager-c13feb9767ac.outlocalhost: starting nodemanager, logging to /usr/local/hadoop/logs/yarn-root-nodemanager-c13feb9767ac.out

1. 运行 jps 命令 --> 确定。

bash-4.1# jps119 NameNode535 ResourceManager200 DataNode656 Jps319 SecondaryNameNode620 NodeManager

1. 获取 IP 地址 --> 确定。

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

1. 转到浏览器 (Google Chrome v70) --> KO。

使用的地址:172.17.0.2:50070

错误:

This site is unreachable 172.17.0.2 took too long to answer.

你能帮我解决一下吗？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，您需要公开端口。

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(该链接帖子是在 2016 年创建的，在 Docker for Windows 存在之前)，您不需要使用 ifconfig，而是使用 来自 Windows 的 docker-machine ip，而不是容器

就我个人而言，我使用 Docker Compose
