ODP is an easy way for users to connect to the observer, so we support this function in 0.1.1.

You can find a demo below showing how to connect to ODP by obkv-hbase-client-java.

public class ObHTableTestUtil {
    // Please consult your dba for the following configuration.
    public static String  FULL_USER_NAME = "";
    public static String  PASSWORD       = "";
    public static String  ODP_ADDR       = "";
    public static int     ODP_PORT       = 0;
    public static boolean ODP_MODE       = false;
    public static String  DATABASE       = "";

    public static Configuration newConfiguration() {
        Configuration conf = new Configuration();

        conf.set(HBASE_OCEANBASE_FULL_USER_NAME, FULL_USER_NAME);
        conf.set(HBASE_OCEANBASE_PASSWORD, PASSWORD);
        conf.set(HBASE_OCEANBASE_ODP_ADDR, ODP_ADDR);
        conf.setInt(HBASE_OCEANBASE_ODP_PORT, ODP_PORT);
        conf.setBoolean(HBASE_OCEANBASE_ODP_MODE, ODP_MODE);
        conf.set(HBASE_OCEANBASE_DATABASE, DATABASE);
    }

    public static OHTableClient newOHTableClient(String tableName) {
        return new OHTableClient(tableName, newConfiguration());
    }
}
