首先添加Hbase的依赖

1、获取Hbase的连接对象

2、读取本地文件

3、put到Hbase表中(提前在Hbase中创建表,并设置好列族)

4、释放资源

import com.duan.utils.HbaseUtil;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.TableName;
import org.apache.hadoop.hbase.client.*;

import java.io.BufferedReader;
import java.io.FileReader;
import java.util.ArrayList;
import java.util.List;

public class LoadData {
    public static void main(String[] args) throws Exception {
        //获取Hbase的连接对象
        Configuration conf = HBaseConfiguration.create();
        // 设置zk的地址
        conf.set("hbase.zookeeper.quorum" , "doit01:2181,doit02:2181,doit03:2181");
        // 获取连接对象
        Connection conn = ConnectionFactory.createConnection(conf);

        BufferedMutator mutator = conn.getBufferedMutator(TableName.valueOf("tb_stu2"));
        List<Mutation>list=new ArrayList<>();
        BufferedReader br = new BufferedReader(new FileReader("C:\\Users\\DHG\\Desktop\\user.txt"));
        String line = null ;
        while ((line=br.readLine())!=null){
            //u001,zss,23,M
            String[] split = line.split(",");
            Put put = new Put(split[0].getBytes());//u001行数据
            put.addColumn("cf".getBytes(),"name".getBytes(),split[1].getBytes());
            put.addColumn("cf".getBytes(),"age".getBytes(),split[2].getBytes());
            put.addColumn("cf".getBytes(),"gender".getBytes(),split[3].getBytes());
            list.add(put);
        }
        //批次操作对象
        mutator.mutate(list); //缓存、类似于put操作
        mutator.flush(); //手动刷写到Hbase中的HDFS上

        mutator.close();//关闭资源

    }
}

user.txt数据:

u001,zss,23,M
u002,lss,22,F
u003,lls,33,M
u004,cls,43,F

执行程序,即可将本地数据写到Hbase中.
