Use Zookeeper in HBase
----------------------

                 Key: HBASE-546
                 URL: https://issues.apache.org/jira/browse/HBASE-546
             Project: Hadoop HBase
          Issue Type: Improvement
            Reporter: Bryan Duxbury
            Priority: Trivial


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.
