Jay Guo updated MESOS-6629:
---------------------------
Comment: was deleted
(was: bq. {{FrameworkInfo.roles}} must not contain duplicate entries.
Do we want subscription to fail for duplicate roles or we simply deduplicate it
and generate a warning? For the latter case we could change {{roles::parse}} to
return std::set and reuse it for both framework and master's {{-- roles}}.
Currently, master throws out warning for duplicate roles in {{-- roles}}:

> Add master validation of FrameworkInfo.roles.

> set at a time.
> (2) If {{FrameworkInfo.roles}} is set, then the MULTI_ROLE framework
> capability must be provided.
> (3) If the MULTI_ROLE framework capability is provided, then
> {{FrameworkInfo.role}} must not be set.
> (4) {{FrameworkInfo.roles}} must not contain duplicate entries.
