Hadoop on Docker

Use this to get a quick version of Hadoop to run on Docker.

1. Install Docker
   

2. Clone this repository

git clone https://github.com/silicoflare/docker-hadoop

3. Navigate to the directory

cd docker-hadoop

4. Build the docker image (you may need to use sudo)

docker build -t hadoop .

5. Wait for the build to finish
   

6. Create a new container using the newly created image

docker run -it --name anyname hadoop bash

7. Once the Docker prompt appears, execute the following commands one by one:

service ssh restart
stop-all.sh
hdfs namenode -format
start-all.sh
jps

8. From the next time, just run this to open the prompt. Use the same name that you used to create the container.

docker start anyname
docker exec -it anyname bash

Once in, execute:

service ssh restart
stop-all.sh
start-all.sh
jps
