HBase application developers create highly-available HBase tables programmatically using the Java API, as shown in the following example:
HTableDescriptor htd = new HTableDescriptor(TableName.valueOf("test_table"));
htd.setRegionReplication(2);
...
admin.createTable(htd);
This example creates a table named test_table that is replicated to
one secondary region. To replicate test_table to two secondary regions,
pass 3 as a parameter to the setRegionReplication()
method.
