----------------------------------
Summary: Add support for master capabilities
Key: MESOS-5675
URL: https://issues.apache.org/jira/browse/MESOS-5675
Project: Mesos
Issue Type: Improvement
Components: master
Reporter: Neil Conway
Right now, frameworks can advertise their capabilities to the master via the
{{FrameworkInfo}} they use for registration/re-registration. This allows
masters to provide backward compatibility for old frameworks that don't support
new functionality.
To allow new frameworks to support backward compatibility with old masters, the
inverse concept would be useful: masters would tell frameworks which
capabilities are supported by the master, which the frameworks could then use
to decide whether to use features only supported by more recent versions of the
master.
For now, frameworks can workaround this by looking at the master's version
number, but that seems a bit fragile and hacky.
