> HBase cluster isn't always setup along with a DNS server. But regionservers
> now register their hostnames in zookeeper, which bring some inconvenience
> when regionserver isn't in one DNS server. In such situation, clients have to
> maintain the ip/hostname mapping in their /etc/hosts files in order to
> resolve the hostname returned from zookeeper to the right address.
> However, this causes a lot of pain for clients to maintain the mapping,
> especially when adding new machines to the cluster, or some machines' address
> changed due to some reason. All clients need to update their host mapping
> files.
> The issue is to address this problem above, and try to add an option to let
> each regionserver record themself by ip address, instead of hostname only.
