value for uri_folder?

[rsignell]

I'm trying to run this test, and while I've successfully created the environment and cluster using the Dask ML CLI as described, when I try to run the job I get:

(base) rsignell@OSC:~/repos/dask-on-azureml-sample$ az ml job create -g $GROUP -w $WORKSPACE --file job.yml

I'm guessing that I need to specify a valid output location in the job.yml, right?
Like setting uri_folder to blob storage that the cluster has access to?
Or perhaps we have another type of problem?
