Apache HBase JavaAPI 刪除數據

根據rowkey刪除數據

package com.czxy.demo01;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.TableName;
import org.apache.hadoop.hbase.client.Connection;
import org.apache.hadoop.hbase.client.ConnectionFactory;
import org.apache.hadoop.hbase.client.Delete;
import org.apache.hadoop.hbase.client.Table;

public class Test16 {
    /**
     * 刪除數據
     * @param args
     */
    public static void main(String[] args) throws Exception{
        //獲取連接
        Configuration configuration = HBaseConfiguration.create();
        configuration.set("hbase.zookeeper.quorum","hadoop01:2181,hadoop02:2181,hadoop03:2181");
        Connection connection = ConnectionFactory.createConnection(configuration);

        Table myuser = connection.getTable(TableName.valueOf("myuser"));
        Delete delete = new Delete("0001".getBytes());

        myuser.delete(delete);
        myuser.close();
    }
}

刪除表操作

package com.czxy.demo01;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.TableName;
import org.apache.hadoop.hbase.client.Admin;
import org.apache.hadoop.hbase.client.Connection;
import org.apache.hadoop.hbase.client.ConnectionFactory;

public class Test17 {
    /**
     * 刪除表操作
     * @param args
     */
    public static void main(String[] args)throws Exception {
        //獲取連接
        Configuration configuration = HBaseConfiguration.create();
        configuration.set("hbase.zookeeper.quorum","hadoop01:2181,hadoop02:2181,hadoop03:2181");
        Connection connection = ConnectionFactory.createConnection(configuration);
        
        Admin admin = connection.getAdmin();
        admin.disableTable(TableName.valueOf("myuser"));
        admin.deleteTable(TableName.valueOf("myuser"));

        admin.close();
        connection.close();
    }
}
