import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.HColumnDescriptor;
import org.apache.hadoop.hbase.HTableDescriptor;
import org.apache.hadoop.hbase.MasterNotRunningException;
import org.apache.hadoop.hbase.client.HBaseAdmin;
import org.apache.hadoop.hbase.client.HTable;

public class Test {

    public static void main(String args[]) throws Exception {

        Configuration config = HBaseConfiguration.create();
        HBaseAdmin admin = null;
        try {
            // HBaseAdmin is where all the "DDL" like operations take place in
            // HBase
            admin = new HBaseAdmin(config);
        } catch (MasterNotRunningException e) {
            throw new Exception(
                    "Could not setup HBaseAdmin as no master is running, did you start HBase?...");
        }

        if (!admin.tableExists("testTable")) {
            admin.createTable(new HTableDescriptor("testTable"));

            // disable so we can make changes to it
            admin.disableTable("testTable");

            // lets add 2 columns
            admin.addColumn("testTable", new HColumnDescriptor("firstName"));
            admin.addColumn("testTable", new HColumnDescriptor("lastName"));

            // enable the table for use
            admin.enableTable("testTable");

        }

        // get the table so we can use it in the next set of examples
        HTable table = new HTable(config, "testTable");
    }
