Only 1 datanode is running after start the cluster

Thanks for sharing this docker. It is really helpful for hadoop development. Currently when I pull the latest source and run the containers with docker-compose, the cluster runs well with only 1 datanode.

Wondering how to start 3 datanode at least for development purpose?

Thanks.

You need to change docker-compose.yml file. Watch this
