Does "coordinator show" work for you?

11xor6 commented 11 years ago

No, same error I believe

Oh this is an error in the provisioner/coordinator... it is getting duplicates in the list of coordinators for some reason.

11xor6 commented 11 years ago

I dug into the code and apparently a coordinator keeps a list of "other coordinators," but the coordinator also somehow adds itself to that list causing duplicates to be returned by io.airlift.airship.coordinator.Coordinator.getCoordinators().

I don't have time to finish trying to fix this issue, but this is a report of what is actually going wrong.
