> ZooKeeper is used a a monitoring tool: we use znode and we start the recovery 
> process when a znode is deleted by ZK because it got a timeout. This timeout 
> is defaulted to 90 seconds, and often set to 30s
> However, some HW issues could be detected by specialized hw monitoring tools 
> before the ZK timeout. For this reason, it makes sense to offer a very simple 
> function to mark a RS as dead. This should not take in
> It could be a hbase shell function such as
> considerAsDead ipAddress|serverName
> This would delete all the znodes of the server running on this box, starting 
> the recovery process.
> Such a function would be easily callable (at callers risk) by any fault 
> detection tool... We could have issues to identify the right master & region 
> servers around ipv4 vs ipv6 vs and multi networked boxes however.
