Jean-Daniel Cryans commented on HBASE-546:
------------------------------------------

Completely  overlooked something. This solution misses the fact that if we want to start the processes with start-hbase.sh we need a file with the zk servers in it (like st^ack was saying on IRC, I just woke up). So it means having to duplicate the information. But, if ZK cluster is for more than just HBase usage, leaving  the zkservers file blank would enable this really easily.

> 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.
