The documentation for druid.selectors.coordinator.serviceName says that it is needed only by realtime nodes for handoffs.

so for upgrading to 0.8.3, will the druid.selectors.coordinator.serviceName value need to be:
druid.selectors.coordinator.serviceName = coordinator
druid.selectors.coordinator.serviceName = druid/coordinator
