一、简单模式的实现的代码如下：

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.Cell;
import org.apache.hadoop.hbase.CellUtil;
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.TableName;
import org.apache.hadoop.hbase.ZooKeeperConnectionException;
import org.apache.hadoop.hbase.client.Delete;
import org.apache.hadoop.hbase.client.Get;
import org.apache.hadoop.hbase.client.HBaseAdmin;
import org.apache.hadoop.hbase.client.HTable;
import org.apache.hadoop.hbase.client.Put;
import org.apache.hadoop.hbase.client.Result;
import org.apache.hadoop.hbase.client.ResultScanner;
import org.apache.hadoop.hbase.client.Scan;
import org.apache.hadoop.hbase.mapreduce.TableInputFormat;
import org.apache.hadoop.hbase.util.Bytes;
import org.apache.hadoop.security.UserGroupInformation;

  }
    
 }
}


二、有接口类和实现类的实现代码如下：



1、接口类

package local.interfaces;

import java.util.List;

import org.apache.hadoop.hbase.client.Put;
import org.apache.hadoop.hbase.client.Result;

public interface HBaseDAO {

	public void save(Put put, String tableName) ;
	public void insert(String tableName, String rowKey, String family, String quailifer, String value) ;
	public void insert(String tableName, String rowKey, String family, String quailifer[], String value[]) ;
	
	public void save(List Put, String tableName) ;
	
	public Result getOneRow(String tableName, String rowKey) ;
	
	public List getRows(String tableName, String rowKey_like) ;
	
	public List getRows(String tableName, String rowKeyLike, String cols[]) ;
	
	public List getRows(String tableName, String startRow, String stopRow) ;
	
	public void deleteRecords(String tableName, String rowKeyLike);
	public   void deleteTable(String tableName);
	public   void createTable(String tableName, String[] columnFamilys);
}

2、实现类
package local.impl;

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import local.interfaces.HBaseDAO;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.Cell;
import org.apache.hadoop.hbase.CellUtil;
import org.apache.hadoop.hbase.HColumnDescriptor;
import org.apache.hadoop.hbase.HTableDescriptor;
import org.apache.hadoop.hbase.KeyValue;
import org.apache.hadoop.hbase.MasterNotRunningException;
import org.apache.hadoop.hbase.TableName;
import org.apache.hadoop.hbase.ZooKeeperConnectionException;
import org.apache.hadoop.hbase.client.Delete;
import org.apache.hadoop.hbase.client.Get;
import org.apache.hadoop.hbase.client.HBaseAdmin;
import org.apache.hadoop.hbase.client.HConnection;
import org.apache.hadoop.hbase.client.HConnectionManager;
import org.apache.hadoop.hbase.client.HTable;
import org.apache.hadoop.hbase.client.HTableInterface;
import org.apache.hadoop.hbase.client.Put;
import org.apache.hadoop.hbase.client.Result;
import org.apache.hadoop.hbase.client.ResultScanner;
import org.apache.hadoop.hbase.client.Scan;
import org.apache.hadoop.hbase.filter.PrefixFilter;
import org.apache.hadoop.hbase.mapreduce.TableInputFormat;
import org.apache.hadoop.security.UserGroupInformation;
