When accessing the HBase web interface (e.g. http://<ANALYTICS>:60010), the HBase Region Servers do not appear except any running on the HMaster server.
HBase relies on the regionservers and hbase-site.xml files to manage instances in its environment. Both of these files are located in /opt/interset/hbase/conf and must be copied to this directory on all remote HBase installations.
The regionservers file contains the hostnames of all Region Servers in the environment. These values should be listed 1 per line, and should correspond with the entries in the /etc/hosts file*.
The hbase-site.xml file dictates where the HMaster is located, in the hbase.rootdir parameter, as well as a pointer to the Zookeeper instance managing the HBase configuration in the hbase.zookeeper.quorum parameter. Likewise, these should correspond with an entry in the /etc/hosts file.
If these files have been copied to all servers, also ensure that they are owned by the proper user (interset) and have appropriate permissions (minimum 400/r--).
*Apache best practices note that hostnames used in its configuration files should be hard coded in the systems' /etc/hosts file. More information on this can be found @ https://wiki.apache.org/hadoop/UnknownHost.
