Andrei Savu commented on WHIRR-325:
-----------------------------------

> We could use this along with runScriptOnNode() to pass IP addresses, etc. Is this what you had in mind?

Exactly. 

> One possible downside to this approach is that using "whirr run-script" wouldn't be able to set these environment variables

We could rewrite "whirr run-script" in terms of runScriptOnNode. 

Actually I think it would be useful to have a runScriptOnNode method on the ClusterController that would set all the required environment variables and we could call that by using an executor service.

> Many of the bash functions have a cloud provider option (-c) that they use to determine how to find the local public/private IP address, or the local data directory (/mnt vs /data, for example).
> We should pass what is needed (e.g. IP addresses, directories), or at least put the code in a common function.
