Hadoop学习笔记之HBase客户端程序开发

时间：2021-12-05 23:19:42

先说一下今天的学习目标：

今天我们将使用Java在Window7客户端上对HBase进行调用，进行创建表，插入行，读取行，读取所有表记录，删除表等基础操作。

下面开始今天的学习

1.开启hadoop,并测试是否可用

  • start-all.sh
    Hadoop学习笔记之HBase客户端程序开发
    Warning不用管，不影响使用。
  • jps
    Hadoop学习笔记之HBase客户端程序开发
  • hadoop fs -ls /
    Hadoop学习笔记之HBase客户端程序开发

2.开启HBase

  • start-hbase.sh
    Hadoop学习笔记之HBase客户端程序开发
  • hbase shell
    Hadoop学习笔记之HBase客户端程序开发
  • jps 检测Java进程
    Hadoop学习笔记之HBase客户端程序开发

3.开始Eclipse 连接HDFS

Hadoop学习笔记之HBase客户端程序开发

连接成功

4.创建项目Hadoop_5_HBase开始编程

我们将要创建HBaseHelper.java和HBaseInvoke.java两个类。

HBaseHelper：主要实现对HBase的连接和对数据库的构建、创建表、删除表、插入记录、删除记录、获取一条记录、获取所有记录等功能。

HBaseInvoke ：主要实现通过对HBaseHelper的调用实现对HBase的基础操作的测试。

HBaseHelper.java 代码如下：

package com.hugy.hadoop;

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

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.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;

public class HBaseHelper {
	private Configuration conf;// 配置器
	private HBaseAdmin admin;// HBase管理员

	/**
	 * 获取HBase配置器
	 * 
	 * @param conf
	 *            Hadoop配置器
	 * @throws IOException
	 */
	public HBaseHelper(Configuration conf) throws IOException {
		this.conf = HBaseConfiguration.create(conf);
		this.admin = new HBaseAdmin(this.conf);
		System.out.println("创建HBase配置成功！");
	}

	/**

	 */
	public HBaseHelper() throws IOException {
		Configuration cnf = new Configuration();
		this.conf = HBaseConfiguration.create(cnf);
		this.admin = new HBaseAdmin(this.conf);
		System.out.println("创建HBase配置成功！");
	}

	/**

	 */
	public void createTable(String tableName, String colFamilies[])
			throws IOException {
		if (this.admin.tableExists(tableName)) {
			System.out.println("Table: " + tableName + " already exists !");
		} else {
			HTableDescriptor dsc = new HTableDescriptor(tableName);
			int len = colFamilies.length;
			for (int i = 0; i < len; i++) {
				HColumnDescriptor family = new HColumnDescriptor(colFamilies[i]);
				dsc.addFamily(family);
			}
			admin.createTable(dsc);
			System.out.println("创建表" + tableName + "成功");
		}

	}

	/**
	 * 删除表
	 * 
	 * @param tableName
	 *            表名
	 * @throws IOException
	 */
	public void deleteTable(String tableName) throws IOException {
		if (this.admin.tableExists(tableName)) {
			admin.disableTable(tableName);
			System.out.println("禁用表" + tableName + "!");
			admin.deleteTable(tableName);
			System.out.println("删除表成功!");
		} else {
			System.out.println(tableName + "表不存在 !");
		}
	}

	/**

	 *            值

	 */
	public void insertRecord(String tableName, String rowkey, String family,
			String qualifier, String value) throws IOException {
		HTable table = new HTable(this.conf, tableName);
		Put put = new Put(rowkey.getBytes());
		put.add(family.getBytes(), qualifier.getBytes(), value.getBytes());
		table.put(put);
		System.out.println(tableName + "插入key:" + rowkey + "行成功!");
	}

	/**

	public void deleteRecord(String tableName, String rowkey)
			throws IOException {

		table.delete(del);
		System.out.println(tableName + "删除行" + rowkey + "成功!");
	}

	/**

	public Result getOneRecord(String tableName, String rowkey)
			throws IOException {
		HTable table = new HTable(this.conf, tableName);
		Get get = new Get(rowkey.getBytes());
		Result rs = table.get(get);
		return rs;
	}

	/**
	 * 获取所有数据

	public List<Result> getAllRecord(String tableName) throws IOException {
		HTable table = new HTable(this.conf, tableName);
		Scan scan = new Scan();
		ResultScanner scanner = table.getScanner(scan);
		List<Result> list = new ArrayList<Result>();
		for (Result r : scanner) {
			list.add(r);
		}
		scanner.close();
		return list;
	}
}

HBaseInvoke.java代码如下：

package com.hugy.hadoop;

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

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.KeyValue;
import org.apache.hadoop.hbase.client.Result;

public class HBaseInvoke {

	/**
	 * @param args
	 * @throws IOException
	 */
	public static void main(String[] args) throws IOException {
		System.out.println("HBase 操作开始...");
		// 1.初始化HBaseOperation
		Configuration conf = new Configuration();
		// 与hbase/conf/hbase-site.xml中hbase.zookeeper.quorum配置的值相同
		conf.set("hbase.zookeeper.quorum", "hadoop");
		// 与hbase/conf/hbase-site.xml中hbase.zookeeper.property.clientPort配置的值相同
		conf.set("hbase.zookeeper.property.clientPort", "2181");
		HBaseHelper hbase = new HBaseHelper(conf);
		// 2.测试相应操作
		// 2.1创建表
		String tableName = "blog";
		hbase.deleteTable(tableName);
		String colFamilies[] = { "article", "author" };
		hbase.createTable(tableName, colFamilies);
		// 2.2插入一条记录
		hbase.insertRecord(tableName, "1", "article", "title", "Hadoop学习资料");
		hbase.insertRecord(tableName, "1", "author", "name", "hugengyong");
		hbase.insertRecord(tableName, "1", "article", "content", "Hadoop学习，HBase学习-http://blog.csdn.net/hugengyong");

		// 2.3查询一条记录
		Result rs1 = hbase.getOneRecord(tableName, "1");
		for (KeyValue kv : rs1.raw()) {
			System.out.println(new String(kv.getRow()));
			System.out.println(new String(kv.getFamily()));
			System.out.println(new String(kv.getQualifier()));
			System.out.println(new String(kv.getValue()));
		}
		// 2.4查询整个Table
		List<Result> list = null;
		list = hbase.getAllRecord(tableName);
		Iterator<Result> it = list.iterator();
		while (it.hasNext()) {
			Result rs2 = it.next();
			for (KeyValue kv : rs2.raw()) {
				System.out.print("row key is : " + new String(kv.getRow()));
				System.out.print("family is  : " + new String(kv.getFamily()));
				System.out.print("qualifier is:"
						+ new String(kv.getQualifier()));
				System.out.print("timestamp is:" + kv.getTimestamp());
				System.out.println("Value  is  : " + new String(kv.getValue()));
			}

		}

	}

}

执行结果如下：
