Niklas Quarfot Nielsen commented on MESOS-2841:
-----------------------------------------------

Great idea [~jdef]! Let us take a look at how this would look like.

Changing those during reregistration may need a special path and we need to 
make sure they are accessible through the state endpoints.

We introduce the notion of webui_url - maybe they should both be encapsulated 
in a SharedFrameworkInfo message (without any ties to the name - feel free to 
come up with another über message to encapsulate this in).

We also have a 'framework capability' message now (introduced during the 
oversubscription work). Would it make sense to put in there perhaps?

I have no strong preference at this point, but just exploring different 
approaches :)

> A framework instance may offer specific capabilities to the cluster: storage, 
> smartly-balanced request handling across deployed tasks, access to 3rd party 
> services outside of the cluster, etc. These capabilities may or may not be 
> utilized by all, or even most mesos clusters. However, it should be possible 
> for processes running in the cluster to discover capabilities or features of 
> frameworks in order to achieve a higher level of functionality and a more 
> seamless integration experience across the cluster.
> A rich discovery API attached to the FrameworkInfo could result in some form 
> of early lock-in: there are probably many ways to realize cross-framework 
> integration and external services integration that we haven't considered yet. 
> Rather than over-specify a discovery info message type at the framework level 
> I think FrameworkInfo should expose a **very generic** way to supply metadata 
> for interested consumers (other processes, tasks, etc).
> Adding a Labels field to FrameworkInfo reuses an existing message type and 
> seems to fit well with the overall intent: attaching generic metadata to a 
> framework instance. These labels should be visible when querying a mesos 
> master's state.json endpoint.
