Using hbase-orm in BigTable

Question

I am trying to use hbase-orm in Bigtable (I am running the code on Bigtable Emulator). I keep getting this exception:

Here is the record class:

here the DAO class:

import com.flipkart.hbaseobjectmapper.AbstractHBDAO;
import org.apache.hadoop.hbase.client.Connection;
import java.io.IOException;

public class CitizenDAO extends AbstractHBDAO<String, Citizen> {

    public CitizenDAO(Connection connection) throws IOException {
        super(connection); 
    }
}

Here is the main class:

import com.google.cloud.bigtable.hbase.BigtableConfiguration;
import org.apache.hadoop.hbase.client.Connection;

import java.io.IOException;

public class Main {
    public static void main(String[] args) {
        try (Connection connection = BigtableConfiguration.connect("projectId", "instanceId")) {
            CitizenDAO citizenDao = new CitizenDAO(connection);
            String rowKey = citizenDao.persist(new Citizen("IND", 1, "Suhaib", (short) 5, 15, 155L));
            System.out.println(rowKey);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

Any advice to solve the issue? I don't know If I can use hbase-orm in Bigtable or not, since I am a beginner in Bigtable and HBase. Thanks.

I found the solution by myself, The issue was with connecting to Bigtable Emulator it was the wrong way here is the correct way :

Configuration conf = BigtableConfiguration.configure("projectId", "instanceId");
conf.set(BigtableOptionsFactory.BIGTABLE_EMULATOR_HOST_KEY, "localhost:8086");
Connection connection = BigtableConfiguration.connect(conf);
Admin admin = connection.getAdmin();
CitizenDAO citizenDao = new CitizenDAO(connection);
String rowKey = citizenDao.persist(new Citizen("IND", 1, "Suhaib", (short) 5, 15, 155L));
Citizen citizen = citizenDao.get("IND|1");
System.out.println(citizen.getName());
