> Zookeeper =~ Chubby. This means that we could take advantage of a distributed lock manager to coordinate things like failover masters, regionservers staying online when master is dead, atomic region->regionserver assignments, etc. There are a lot of opportunities for improvements here. Please add discussions of particular features in comments or sub-tasks.
