ChenKai commented on HBASE-11768:
---------------------------------
[~stack]
We run HBase cluster on k8s, and it seems to get the wrong ip(hostname) back
with this patch when invoking *regionServerStartup* and
*handleReportForDutyResponse* method.
The error is {color:red}"Master passed us a different hostname to use;
xxxxx"{color}.
I am not sure if there's something wrong with k8s DNS, so we returned and use
*hbase.master(regionserver).hostname*.

> 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.
