Open nlamblin opened 5 years ago

I try to use Hadoop with Docker Toolbox on Windows 10 Family. So I followed this setup : https://linoxide.com/cluster/setup-single-node-hadoop-cluster-docker/

  1. Download the image --> OK

  2. Run the container --> OK

    $ docker run -it sequenceiq/hadoop-docker:2.7.1 /etc/bootstrap.sh -bash/
Starting sshd:                                             [  OK  ]

  3. Run jps command --> OK

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

  4. Get IP adress --> OK

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

  5. Go to browser (Google Chrome v70) --> KO Address used : 172.17.0.2:50070

Error :

This site is unreachable 172.17.0.2 took too long to answer.

Can you help me to fix it please? If you need more informations ask me.

Thanks.

You should not use default command to create the docker container, if you want to access the hadoop web sites. The default command does not expose the ports out of the container. Try this command to create a new container which mapping 8088 and 50070 port to localhost. docker run -it -p 8088:8088 -p 50070:50070 sequenceiq/hadoop-docker:2.7.1 /etc/bootstrap.sh -bash Use http://localhost:50070 to browse hadoop web site.

Good Luck!

If you want to access hadoop website outside your localhost as below http://:50070/

then you can run below command

sudo docker run -it -p 8088:8088 -p 50070:50070 --hostname sequenceiq/hadoop-docker:2.7.0 /etc/bootstrap.sh -bash
