nimbus.host value in the case of multiple mesos masters

Do you have a typo here? mesos.master.url: zk://master1:2181master2:2181,master3:2181/mesos

It seems at the very least that you're missing a comma.

@JessicaLHartog yep it was a typo.
Thanks

@salimane : we're confused -- are you saying it was a typo in the question or a typo in your config? (because I see that you updated the question).

Furthermore, I'm confused about this statement "each mesos master running storm-nimbus" --> are you saying that you're running 3 copies of storm-nimbus? If so, then that is your problem -- you are indeed running 3 frameworks. You should only run that command once at a time.

@erikdw so even though I have 3 mesos masters, I should only run storm-nimbus on one of the master. So if that master goes down, the storm cluster goes down. I thought we would have some HA by running storm on mesos because mesos already have HA if you have multiple mesos masters.
Thanks

@salimane : the choice of where to run your MesosNimbus is orthogonal to where you run your mesos-masters. i.e., in a normal production mesos cluster a framework's scheduler (the MesosNimbus in our case) would definitely not be running on one of the mesos-master hosts.

Also, if the MesosNimbus goes down, the cluster doesn't go down. Just the MesosNimbus / storm-nimbus does. The workers keep running (for the failover period, which is configurable through mesos.master.failover.timeout.secs).

@erikdw ah I see
Thanks

@salimane ^ please see my updates to my comment above.
