Hi Diptanu, If you choose to use the replicated log <http://mesos.apache.org/blog/mesos-0-17-0-released-featuring-autorecovery/> as the backend for registrar <http://mesos.apache.org/blog/mesos-0-19-0-released/>, you're gonna tell each master how many masters are there in the cluster. Each registrar operation (e.g. admit) need to be approved by a quorum of masters. In almost all the cases, you have the following equation:
(quorum * 2 - 1) == # masters So if you have 3 masters, quorum should be 2. I know that Ben Mahler is working a runbook which will document all these. - Jie On Tue, Jul 1, 2014 at 2:57 PM, Diptanu Choudhury <[email protected]> wrote: > Hi Guys, > > Can someone explain what does --quorum tells Mesos Master?
