Monitoring Secondary Region Replicas
You can access the HBase Master server user interface and monitor the secondary region replicas.
HBase provides highly available tables by replicating table regions. All replicated regions have a unique replica ID.
The replica ID for a primary region is always 0. The HBase web-based interface displays the replica IDs for all
defined table regions. In the following example, the table
t1 has two regions. The secondary
region is identified by a replica ID of 1.
To access the HBase Master Server user interface, point your browser to port 16010.
