Subject [jira] [Created] (MESOS-86) Expose master url to the scheduler
Date Wed, 16 Nov 2011 02:04:52 GMT
Expose master url to the scheduler
----------------------------------

                 Key: MESOS-86
                 URL: https://issues.apache.org/jira/browse/MESOS-86
             Project: Mesos
          Issue Type: New Feature
            Reporter: Vinod Kone


Introduce new / augment old api calls (callbacks) to expose the master url.

Currently there is no way for the scheduler to know what the leading master is. It would be
useful for scheduler's to know this information (e.g: pointing to the webui of the leading
master). Here is the plan:

1) Augment registered() callback to included this info
2) Implement new callback re-registered() that gets called whenever a master re-election happens.
This also contains the new master url.
3) Also implement a new callback masterLost()  that gets called whenever the current master
loses election.
