When HBase clusters running on unusual networks as such as NAT cloud environments or physical machines with multiple IP's per network interface, it would be best practice to specify,
1. Which IP interface to which HBase master or region-server will bind and
2. What hostname HBase will advertise in Zookeeper both for a master or region-server process
In multihomed hosts you may face following error,
In order to overcome this behavior, we need to force the HMaster to receive the hostname of the Region server by setting below property in hbase-site.xml.
The hostname can be either fully qualified domain name(FQDN) or host name.
The above configuration can be done in cluster manager UI as follows.
Step 1: Go to configuration from Administration menu and select HBase.
Step 2: Select each region servers one by one and add the property in hbase-site.xml
Step 3: Save the changes and restart the HBase services.
