@tommy Xiao the goal of our R&D work is precisely to have distant clusters collaborating together, so we aren't really interested in having both clusters on the same data center.

One cluster could occasionally connect to the other to schedule some of his jobs to run there, but in a normal situation, each side would only run jobs locally with its own scheduling capabilities. Thus, a centralized meta-cluster running on top of everything and supporting all the scheduling is not really what we are interested in. I see it more like a brief extension of the clusters' scheduling power. > > ---- > Da (Klaus), Ma (马达) | PMP® | Advisory Software Engineer > Platform Symphony/DCOS Development & Support, STG, IBM GCG > +86-10-8245 4084 | [email protected] | http://k82.me > > On Mon, Nov 30, 2015 at 8:01 PM, tommy xiao <[email protected]> wrote: > >> run two slave in same node is bad idea on production env. i only say, why >> not install two cluster in same DC? >> >> 2015-11-30 14:20 GMT+08:00 Chengwei Yang <[email protected]>: >> >>> On Fri, Nov 27, 2015 at 04:16:44PM +0100, Elouan Keryell-Even wrote: >>> > Hi, >>> > >>> > I don't think this is possible yet, but is it planned some day to be >>> able to >>> > work with multiple active Mesos masters? >>> > >>> > I mean, not just a high-availability configuration with one elected >>> master and >>> > a few others idle masters (in case of failure), but really two masters >>> > exploiting a shared pool of slaves. >>> > >>> > >>> > Our use case: >>> > >>> > We are using Mesos to manage resources of two separated clusters.
