1.编程实现以下指定功能

（1）列出HBase所有的表的相关信息，例如表名

import java.io.IOException;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.*;
import org.apache.hadoop.hbase.client.*;

public class ExampleForHBase {
    public static Configuration configuration;
    public static Connection connection;
    public static Admin admin;
    /**
     * @param args
     */
    //建立连接
    public static void init(){
        configuration  = HBaseConfiguration.create();
        configuration.set("hbase.rootdir","hdfs://localhost:9000/hbase");
        try{
            connection = ConnectionFactory.createConnection(configuration);
            admin = connection.getAdmin();
        }catch (IOException e){
            e.printStackTrace();
        }
    }
    //关闭连接
    public static void close(){
        try{
            if(admin != null){
                admin.close();
            }
            if(null != connection){
                connection.close();
            }
        }catch (IOException e){
            e.printStackTrace();
        }
    }
    
    /**
     * 查看已有表
     * @throws IOException
     */
    public static void listTables() throws IOException {
        init();
        HTableDescriptor hTableDescriptors[] = admin.listTables();
        for(HTableDescriptor hTableDescriptor :hTableDescriptors){
            System.out.println(hTableDescriptor.getNameAsString());
        }
        close();
    }
    
    public static void main(String[] args) {
        // TODO Auto-generated method stub
    	ExampleForHBase t =new ExampleForHBase();
        try {
            System.out.println("以下为Hbase 数据库中所存的表信息");
            t.listTables();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

（2）在终端打印出指定的表的所有记录数据

import java.io.IOException;
import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.*;
import org.apache.hadoop.hbase.client.*;
import java.util.Scanner;

     */
    
  //建立连接
    public static void init(){
        configuration  = HBaseConfiguration.create();
        configuration.set("hbase.rootdir","hdfs://localhost:9000/hbase");
        try{
            connection = ConnectionFactory.createConnection(configuration);
            admin = connection.getAdmin();
        }catch (IOException e){
            e.printStackTrace();
        }
    }
    //关闭连接
    public static void close(){
        try{
            if(admin != null){
                admin.close();
            }
            if(null != connection){
                connection.close();
            }
        }catch (IOException e){
            e.printStackTrace();
        }
    }
  
    /**
     * 根据表名查找表信息
     */
    public static void getData(String tableName)throws  IOException{
        init();
        Table table = connection.getTable(TableName.valueOf(tableName));
        Scan scan = new Scan();
       ResultScanner scanner = table.getScanner(scan);
        
        for(Result result:scanner)
        {
            showCell((result));
        }
        close();
    }
    
    /**
     * 格式化输出
     * @param result
     */
    public static void showCell(Result result){
        Cell[] cells = result.rawCells();
        for(Cell cell:cells){
            System.out.println("RowName(行键):"+new String(CellUtil.cloneRow(cell))+" ");
            System.out.println("Timetamp(时间戳):"+cell.getTimestamp()+" ");
            System.out.println("column Family（列簇）:"+new String(CellUtil.cloneFamily(cell))+" ");
            System.out.println("column Name（列名）:"+new String(CellUtil.cloneQualifier(cell))+" ");
            System.out.println("value:（值）"+new String(CellUtil.cloneValue(cell))+" ");
            System.out.println();
        }
    }
    
    public static void main(String[] args) throws IOException {
        // TODO Auto-generated method stub
    	ExampleForHBase t =new ExampleForHBase();
        System.out.println("请输入要查看的表名");
        Scanner scan = new Scanner(System.in);
        String tableName=scan.nextLine();
        System.out.println("信息如下：");
        t.getData(tableName);
    }
}

 同时，请编程完成以下指定功能：

（1）createTable(String tableName, String[] fields)

       创建表，参数tableName为表的名称，字符串数组fields为存储记录各个域名称的数组。要求当HBase已经存在名为tableName的表的时候，先删除原有的表，然后再创建新的表。

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

import java.io.IOException;

public class ExampleForHBase {
    public static Configuration configuration;
    public static Connection connection;
    public static Admin admin;

    public static void createTable(String tableName, String[] fields) throws IOException {
        init();
        TableName tablename = TableName.valueOf(tableName);
        if (admin.tableExists(tablename)) {
            System.out.println("table is exists!");
            admin.disableTable(tablename);
            admin.deleteTable(tablename);
        }
        HTableDescriptor hTableDescriptor = new HTableDescriptor(tablename);
        for (String str : fields) {
            HColumnDescriptor hColumnDescriptor = new HColumnDescriptor(str);
            hTableDescriptor.addFamily(hColumnDescriptor);
        }
        admin.createTable(hTableDescriptor);
        close();
    }

    public static void init() {
        configuration = HBaseConfiguration.create();
        configuration.set("hbase.rootdir", "hdfs://localhost:9000/hbase");
        try {
            connection = ConnectionFactory.createConnection(configuration);
            admin = connection.getAdmin();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void close() {
        try {
            if (admin != null) {
                admin.close();
            }
            if (null != connection) {
                connection.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        String[] fields = {"Score"};
        try {
            createTable("person", fields);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

（2）scanColumn(String tableName, String column)

       浏览表tableName某一列的数据，如果某一行记录中该列数据不存在，则返回null。要求当参数column为某一列族名称时，如果底下有若干个列限定符，则要列出每个列限定符代表的列的数据；当参数column为某一列具体名称（例如“Score:Math”）时，只需要列出该列的数据。

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.IOException;

public class ExampleForHBase {
    public static Configuration configuration;
    public static Connection connection;
    public static Admin admin;

    public static void addRecord(String tableName, String row, String[] fields, String[] values) throws IOException {
        init();
        Table table = connection.getTable(TableName.valueOf(tableName));
        for (int i = 0; i != fields.length; i++) {
            Put put = new Put(row.getBytes());
            String[] cols = fields[i].split(":");
            put.addColumn(cols[0].getBytes(), cols[1].getBytes(), values[i].getBytes());
            table.put(put);
        }
        table.close();
        close();
    }

    public static void init() {
        configuration = HBaseConfiguration.create();
        configuration.set("hbase.rootdir", "hdfs://localhost:9000/hbase");
        try {
            connection = ConnectionFactory.createConnection(configuration);
            admin = connection.getAdmin();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void close() {
        try {
            if (admin != null) {
                admin.close();
            }
            if (null != connection) {
                connection.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        String[] fields = {"Score:Math", "Score:Computer Science", "Score:English"};
        String[] values = {"99", "80", "100"};
        try {
            addRecord("person", "Score", fields, values);
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
}

（3）scanColumn(String tableName, String column)

       浏览表tableName某一列的数据，如果某一行记录中该列数据不存在，则返回null。要求当参数column为某一列族名称时，如果底下有若干个列限定符，则要列出每个列限定符代表的列的数据；当参数column为某一列具体名称（例如“Score:Math”）时，只需要列出该列的数据。

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.TableName;
import org.apache.hadoop.hbase.client.*;
import org.apache.hadoop.hbase.util.Bytes;

import java.io.IOException;

public class ExampleForHBase {
    public static Configuration configuration;
    public static Connection connection;
    public static Admin admin;

    public static void scanColumn(String tableName, String column) throws IOException {
        init();
        Table table = connection.getTable(TableName.valueOf(tableName));
        Scan scan = new Scan();
        scan.addFamily(Bytes.toBytes(column));
        ResultScanner scanner = table.getScanner(scan);
        for (Result result = scanner.next(); result != null; result = scanner.next()) {
            showCell(result);
        }
        table.close();
        close();
    }

    public static void showCell(Result result) {
        Cell[] cells = result.rawCells();
        for (Cell cell : cells) {
            System.out.println("RowName:" + new String(CellUtil.cloneRow(cell)) + " ");
            System.out.println("Timetamp:" + cell.getTimestamp() + " ");
            System.out.println("column Family:" + new String(CellUtil.cloneFamily(cell)) + " ");
            System.out.println("row Name:" + new String(CellUtil.cloneQualifier(cell)) + " ");
            System.out.println("value:" + new String(CellUtil.cloneValue(cell)) + " ");
        }
    }

    public static void init() {
        configuration = HBaseConfiguration.create();
        configuration.set("hbase.rootdir", "hdfs://localhost:9000/hbase");
        try {

            admin = connection.getAdmin();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    // 关闭连接
    public static void close() {
        try {
            if (admin != null) {
                admin.close();
            }
            if (null != connection) {
                connection.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        try {
            scanColumn("person", "Score");
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
}

（4） modifyData(String tableName, String row, String column)

            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        try {
            modifyData("person", "Score", "Math", "100");
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
}

（5）deleteRow(String tableName, String row)
