Subject Re: Mesos masters and zookeeper running together?
Date Thu, 24 Dec 2015 22:13:24 GMT
zookeeper really wants a dedicated cluster IMO; preferably with SSD
under it - if zookeeper
starts to run slow then everything else will start to bog down. I've
co-hosted it with mesos masters
before now for demo purposes etc. but for production it's probably
worth choosing dedicated hosts.
