Working with HBASE deployed on EC2 instances

Problem

Nearly the same as with HDFS: while we can tell our application to connect to ZooKeeper over public domain name, it still return private domain names for HBase nodes. Unfortunately HDFS trick does not help, even more I found that it prevents proper connection when solution below is applied Read More Here.

Solution

Just go to your hosts file (/etc/hosts on Linux) and add all mappings between EC2 private domain names and there publiс IPs. Once this done HBase client works like a charm.
