Minor fix up.  Add that we can pass --config, fixed copyright, added more to the usage, made
it clear that we are outputting found hosts when no args passed.

Nice script.

> 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.
