Esteban Gutierrez resolved HBASE-22019.
---------------------------------------
    Resolution: Invalid

Thanks for reporting this, [~toopt4]. Please reach out the HBase user [mailing list|https://hbase.apache.org/mailing-lists.html] for this type of this problems since many users have been able to connect to HBase clusters without any problem regardless if the HBase is on different networks.

> 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.

> 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.
