Following this steps you can build and use the image to create Hadoop Single Node Cluster containers.

 $ git clone https://gitlab.com/rancavil/hadoop.git
 $ cd hadoop
 $ docker build -t hadoop:2.9.0 .

To run and create a container execute the next command:

 $ docker run -it --name container-name -p 50070:50070 -p 50075:50075 -p 8088:8088 --hostname your-hostname hadoop:2.9.0 bash

Make sure change container-name by your favorite name and set your-hostname with by your ip or name machine.

When you run the container, at the entrypoint you use the docker-entrypoint.sh shell script that execute the following sequence of commands.

First, start ssh service:

 service ssh start
 bin/hdfs namenode -format

Second, start the services dfs and yarn:

 sbin/start-dfs.sh
 sbin/start-yarn.sh
 bash

Finally, you can use the container.

To check if hadoop container is working go to the url in your browser.

 http://localhost:50070

Notice: the hdfs-site.xml configure has the property.

 <property>
     <name>dfs.permissions</name>
     <value>false</value>
 </property>

This allow you can create directories and upload files throught web ui without authentication. Beware, this is not for production environment.
