Has anyone gotten Hadoop running?

I have been trying for several days now. Doesn’t seem to matter what I do, the containers just keep restarting and never stabilize.

Currently I’m manually starting the namenode-primary manually without any other containers and it wont start cleanly. I keep getting:

Expected state running but got error: Error response from daemon: cannot join network of a non running container:

Anybody have any tips?

3 RancherOS VMs (one for rancher, 2 for Hadoop)
Rancher 1.6.13
The rancher VM is not a rancher host

After tearing it all down, and starting from the bottom up, the namenode is getting this error:
java.lang.IllegalArgumentException: Invalid URI for NameNode address (check fs.defaultFS): file:/// has no authority.

Google says I should be ensuring that the core-site.xml file has the correct entry. Not sure how to change this when it comes from the docker image. I got this started yesterday.

Help? Anyone?
