Hi, generally it should work. Mesos slave gets from ZooKeeper current master IP address. ZooKeepers should be deployed in one datacenter (usually 3 or 5 instances). If you will run on Mesos long term tasks it should be fine. If you would deploy e.g. Spark which tends to have quite short tasks (let's say few hundreds milliseconds), the computations might be slower due to longer communication.
It really depends on your use case, it might be good idea to have a Mesos cluster in each datacenter. However you might try adjusting schedulers so that they would respect slaves location, e.g. prefer allocating task from one framework at the same datacenter, if the resources are available.
