Good day, Apologies if this question has been answered elsewhere, but I've not come across an answer to it. Mesos masters use Zookeeper to master election. Mesos also appears to make use of Paxos, although I am less clear on its intended purpose.
Why the use of two distinct consensus systems? The two should be largely equivalent. I would imagine selecting a single one would be preferable to lower the complexity of the system and to avoid mismatched states (e.g. Zookeeper and Paxos disagreeing about the visibility of Mesos masters if ZK members are not colocated with them). Also, what is Paxos used for within Mesos?
