5. Monitoring Secondary Region Servers

HBase provides highly-available tables by replicating table regions. All replicated regions have a unique replica ID. The replica ID for a primary region server 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 server is identified by a replica ID of 1.
