Checking if Framework has capabilities
Hi,
When I re-register a framework with an updated name, I know that the
FrameworkInfo gets updated, because I can see that on the Mesos web UI.
Similarly, is there a way to check if the framework has capabilities
through the user interface?
Thanks!

We currently don't show the capabilities in the UI. You could add that info to state.json though where we model the framework. Mind sending a patch for that?
Also, the requestReesources() call is currently a no op.

AFAIK, we allow frameworks to update only certain fields for now, see
MESOS-2614 <https://issues.apache.org/jira/browse/MESOS-2614> and MESOS-1784
<https://issues.apache.org/jira/browse/MESOS-1784>. I don't think WebUI was
updated when Capabilities were added. Vinod, any plans to reflect that in
WebUI?
For your second question, my guess is: it's up to allocator.

Well currently there's only Revocable Resources right, so just that.
To reiterate, I initially register a framework with the Revocable Resources
capability, and then reregister it without the Revocable Resources
capability. I want to verify that when reregistration happens, it does not
take into effect that the capability has been dropped after reregistration
and should keep offering revocable resources if asked by the framework.
Ps. If the framework doesn't have the Revocable Resources capability, what
should happen if it requests revocable resources?

Hi Aditi,
what capabilities do you mean?
