+# Hadoop on Docker
+Use this to get a quick version of Hadoop to run on Docker.
+
+1. Install Docker
+<br>
+
+2. Clone this repository
+```bash
+git clone https://github.com/silicoflare/docker-hadoop
+```
+<br>
+
+3. Navigate to the directory
+```bash
+cd docker-hadoop
+```
+<br>
+
+4. Build the docker image (you may need to use sudo)
+```bash
+docker build -t hadoop .
+```
+<br>
+
+5. Wait for the build to finish
+<br>
+
+6. Create a new container using the newly created image
+```bash
+docker run -it --name anyname hadoop bash
+```
+<br>
+
+7. Once the Docker prompt appears, execute the following commands one by one:
+```bash
+service ssh restart
+stop-all.sh
+hdfs namenode -format
+start-all.sh
+jps
+```
+<br>
+
+8. From the next time, just run this to open the prompt. Use the same name that you used to create the container.
+```bash
+docker start anyname
+docker exec -it anyname bash
+```
+
+Once in, execute:
+```bash
+service ssh restart
+stop-all.sh
+start-all.sh
+jps
+```
