----------------------------------
Summary: Register region server in zookeeper by ip address
Key: HBASE-11768
URL: https://issues.apache.org/jira/browse/HBASE-11768
Project: HBase
Issue Type: Improvement
Components: regionserver
Affects Versions: 2.0.0
Reporter: Cheney Sun
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.
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.
