Running the command

clusterdock start topology_cdh --cdh-version 580 --cm-version 581

fails with the following message:

TypeError: __init__() got an unexpected keyword argument 'list_item_delimiter'

The problem is of course that the ConfigObj constructor doesn't expect a 'list_item_delimiter' keyword argument. Should we remove it?

I'm using CDH version 580 and CM version 581 because those are only ones for which a docker image is found by clusterdock, see #44.

You’ve got run pip3 install -r on the tolology’s requirements.txt to pick up the fork that introduces this keyword arg. The keyword arg itself is necessary because of how CM interprets config files. I’ll update the docs to mention this.
