t oo created HBASE-22019:
----------------------------
Summary: Ability to remotely connect to hbase when hbase is hosted
on dynamic IP addresses and
Key: HBASE-22019
URL: https://issues.apache.org/jira/browse/HBASE-22019
Project: HBase
Issue Type: New Feature
Components: IPC/RPC, Zookeeper
Reporter: t oo
Our team's need for this is purely for remote connections (ie personal laptops)
to HBASE (hosted on EC2) to work as hbase connections under the cover connect
to zookeeper (also running on EC2) and attempt to resolve the hostname (not
DNS!) of the machine running zookeeper. From what I've read others re facing
the issue:

Between ec2s I don't get the below error because I can edit /etc/hosts to add
the host name below but don't have root/admin access on other machines to do
the same. Problem is if we have 100s of users wanting to connect to hbase data
then they would all face this /etc/hosts issue.
Example of the error:
