Andrei Savu updated WHIRR-195:
------------------------------

    Attachment: WHIRR-195.patch

This patch needs WHIRR-199 in order to look good :) I haven't added descriptions because the role names should be self explanatory for now.

> Now that service-name is optional I believe that we should display a list of the available roles (with a small description) instead of service names. 
> Similar to: 
> {code}
> $ ./bin/whirr 
> Usage: whirr COMMAND [ARGS]
> where COMMAND may be one of:
>         version  Print the version number and exit.
>  launch-cluster  Launch a new cluster running a service.
> destroy-cluster  Terminate and cleanup resources for a running cluster.
>    list-cluster  List the nodes in a cluster.
> Available roles for instances:
>   nn             hadoop name node
>   jt             hadoop job trackers
>   ... 
> {code}
