本地IDEA向ubantu的hbase传数据

今天用本地idea向hbase中传数据

 

package one;

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 org.apache.hadoop.hbase.util.Bytes;
import org.jruby.RubyProcess;

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


public class test1 {
    public static Configuration conf;

    static{
        conf = HBaseConfiguration.create();
    }
    //4.添加数据put 'user','rowkey','info:name','tony'
    public static void addRow(String tableName,String rowkey,String cf,String column,String value){
        try {
            //对表操作需要使用HbaseAdmin
            Connection connection = ConnectionFactory.createConnection(conf);
            Table t = connection.getTable(TableName.valueOf(tableName));
            //1.表如果存在，请输入其他表名
            if (!isExist(tableName)) {
                System.out.println("表不存在");
            } else {
                //2.用put方式加入数据
                Put p = new Put(Bytes.toBytes(rowkey));
                //3.加入数据
                p.addColumn(Bytes.toBytes(cf),Bytes.toBytes(column),Bytes.toBytes(value));
                t.put(p);

            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    //1.判断一张表是否存在
    public static boolean isExist(String tableName){
        //对表操作需要使用HbaseAdmin

        }
        System.out.println(-1);
        return false;
    }
    public static void main(String[] args) {
            boolean flag=isExist("wjm");
            System.out.println(flag);
            //test1.addRow("wjm","01","info","name","miaokezhuo");
            /*//Student

            int i=0;
            List<Bean> list=cin.cin_txt();
            for (Bean item : list) {
                System.out.println(i);
                i++;
