Description
Currently, the HMaster node(s) must be considered a 'special' node (though not a single point of failover), meaning that the node must be protected more than the other cluster machines or at least specially monitored. Minimally, we always need to ensure that the master is running, rather than letting the system handle that internally. It should be possible to instead have the HMaster be much more available, either in a distributed sense (meaning a bit rewrite) or multiple, dynamically created instances combined with the hot fail-over of masters.
