Hi Michal, 1. While watching some talk I've heard that maybe in the future ZooKeeper > won't be needed. Is this still planned? >
At some point there has been talk of moving towards using etcd instead of ZooKeeper: y ou can look into Jira[0] , and it seems that MESOS-1806[1] is the one that has received the most attention/activity . Others may be able to provide more detailed guidance, but the impression I have is that it may be some time before this becomes available as a Production-ready alternative. > 2. We're using mainly quite large boxes (>= 20 CPUs, >= 48GB RAM). Is it > advised to put Mesos master and warm backup nodes inside ZooKeeper's > cluster? (just to avoid wasting resources). > > There is really no reason not to have Master/ZooKeeper servers co-located - in fact, this is the way DCOS CE is deployed in AWS (or, at least, used to last time I looked into it). Hope this helps!
