Dominic Hamon commented on MESOS-2467:
--------------------------------------
instead of relying on the first character (which can also be '{' in valid json)
perhaps we can instead:
- try JSON parsing, catch failure
- fallback to old parsing
This also means we can deprecate the old parsing behaviour more easily.
> Allow --resources flag to take JSON.

>
> Currently, we used a customized format for --resources flag. As we introduce
> more and more stuffs (e.g., persistence, reservation) in Resource object, we
> need a more generic way to specify --resources.
> For backward compatibility, we can scan the first character. If it is '[',
> then we invoke the JSON parser. Otherwise, we use the existing parser.
