Hi Hadoop developers The other day I created a tool for launching multiple node hadoop cluster on docker container. You can easily launch multiple node hadoop cluster from your Hadoop source code. It is useful for testing and debugging. Actually I often use it before submitting a patch to Hadoop project. https://github.com/Lewuathe/docker-hadoop-cluster <https://github.com/Lewuathe/docker-hadoop-cluster>
And I also updated to build the latest trunk image automatically and upload onto Docker Hub. So you can easily check and test the latest trunk branch in the environment which is more close to actual usage. If you already installed docker and docker-compose, what needed is docker-compose.yml like this. version: '2' services: master: image: lewuathe/hadoop-master ports: - "9870:9870" - "8088:8088" - "19888:19888" - "8188:8188" container_name: "master" slave1: image: lewuathe/hadoop-slave container_name: "slave1" depends_on: - master ports: - "9901:9864" - "8041:8042" slave2: image: lewuathe/hadoop-slave container_name: "slave2" depends_on: - master ports: - "9902:9864" - "8042:8042" The usage in detail is described in the repository. https://github.com/Lewuathe/docker-hadoop-cluster/blob/master/README.md <https://github.com/Lewuathe/docker-hadoop-cluster/blob/master/README.md> I would be glad if you use this tool for developing and debugging and make our development more efficient. Please give me any feedbacks to me. Thanks you! ———————— Kai Sasaki mail: lewua...@me.com <mailto:lewua...@me.com> github: https://github.com/Lewuathe <https://github.com/Lewuathe>
