> Disallow frameworks from modifying FrameworkInfo.roles.
> -------------------------------------------------------
>                 Key: MESOS-6631
>                 URL:
>             Project: Mesos
>          Issue Type: Task
>          Components: master
>            Reporter: Benjamin Mahler

> In "phase 1" of the multi-role framework support, we want to preserve the existing behavior
of single-role framework support in that we disallow frameworks from modifying their role.
> With multi-role framework support, we will initially disallow frameworks from modifying
the roles field. Note that in the case that the master has failed over but the framework hasn't
re-registered yet, we will use the framework info from the agents to disallow changes to the
roles field. We will treat {{FrameworkInfo.roles}} as a set rather than a list, so ordering
does not matter for equality.
> One difference between {{role}} and {{roles}} is that for {{role}} modification, we ignore
it. But, with {{roles}} modification, since this is a new feature, we can disallow it by rejecting
the framework subscription.
> Later, in phase 2, we will allow frameworks to modify their roles, see MESOS-6627.
