HA/Distributed HMaster via RegionServers
----------------------------------------

                 Key: HBASE-5353
                 URL: https://issues.apache.org/jira/browse/HBASE-5353
             Project: HBase
          Issue Type: Improvement
          Components: master, regionserver
    Affects Versions: 0.94.0
            Reporter: Jesse Yates
            Priority: Minor


Currently, the HMaster node must be considered a 'special' node (single point 
of failure), meaning that the node must be protected more than the other 
commodity machines. It should be possible to instead have the HMaster be much 
more available, either in a distributed sense (meaning a bit rewrite) or with 
multiple instances and automatic failover.
