HBase编程 API入门系列之delete（管理端而言）

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了HBase编程 API入门系列之delete（管理端而言）相关的知识，希望对你有一定的参考价值。

　大家，若是看过我前期的这篇博客的话，则

HBase编程 API入门之delete（客户端而言）

　　就知道，在这篇博文里，我是在客户端里删除HBase表的。

　　这里，我带领大家，学习更高级的，因为，在开发中，尽量不能客户端上删除表。

　　所以，在管理端来删除HBase表。采用线程池的方式（也是生产开发里首推的）

package zhouls.bigdata.HbaseProject.Pool;

import java.io.IOException;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.client.HConnection;
import org.apache.hadoop.hbase.client.HConnectionManager;

public class TableConnection {
private TableConnection(){
}
private static HConnection connection = null;
public static HConnection getConnection(){
if(connection == null){
ExecutorService pool = Executors.newFixedThreadPool(10);//建立一个固定大小的线程池
Configuration conf = HBaseConfiguration.create();
conf.set("hbase.zookeeper.quorum","HadoopMaster:2181,HadoopSlave1:2181,HadoopSlave2:2181");
try{
connection = HConnectionManager.createConnection(conf,pool);//创建连接时，拿到配置文件和线程池
}catch (IOException e){
}
}
return connection;
}
}

1、删除不存在的HBase表

hbase(main):062:0> list
TABLE
test_table
test_table2
test_table3
test_table4
4 row(s) in 0.1540 seconds

=> ["test_table", "test_table2", "test_table3", "test_table4"]
hbase(main):063:0>

2、删除存在的HBase表

package zhouls.bigdata.HbaseProject.Pool;

import java.io.IOException;

import zhouls.bigdata.HbaseProject.Pool.TableConnection;

import javax.xml.transform.Result;

public class HBaseTest {

// Delete delete = new Delete(Bytes.toBytes("row_04"));
//// delete.deleteColumn(Bytes.toBytes("f"), Bytes.toBytes("name"));//deleteColumn是删除某一个列簇里的最新时间戳版本。
// delete.deleteColumns(Bytes.toBytes("f"), Bytes.toBytes("name"));//delete.deleteColumns是删除某个列簇里的所有时间戳版本。
// table.delete(delete);
// table.close();

// Scan scan = new Scan();
// scan.setStartRow(Bytes.toBytes("row_01"));//包含开始行键
// scan.setStopRow(Bytes.toBytes("row_03"));//不包含结束行键
// scan.addColumn(Bytes.toBytes("f"), Bytes.toBytes("name"));
// ResultScanner rst = table.getScanner(scan);//整个循环
// System.out.println(rst.toString());
// for (org.apache.hadoop.hbase.client.Result next = rst.next();next !=null;next = rst.next() )
// {
// for(Cell cell:next.rawCells()){//某个row key下的循坏
// System.out.println(next.toString());
// System.out.println("family:" + Bytes.toString(CellUtil.cloneFamily(cell)));
// System.out.println("col:" + Bytes.toString(CellUtil.cloneQualifier(cell)));
// System.out.println("value" + Bytes.toString(CellUtil.cloneValue(cell)));
// }
// }
// table.close();

HBaseTest hbasetest =new HBaseTest();
// hbasetest.insertValue();
// hbasetest.getValue();
// hbasetest.delete();
// hbasetest.scanValue();
// hbasetest.createTable("test_table4", "f");
hbasetest.deleteTable("test_table4");//删除存在的表

}

//生产开发中，建议这样用线程池做
// public void insertValue() throws Exception{
// HTableInterface table = TableConnection.getConnection().getTable(TableName.valueOf("test_table"));
// Put put = new Put(Bytes.toBytes("row_01"));//行键是row_01
// put.add(Bytes.toBytes("f"),Bytes.toBytes("name"),Bytes.toBytes("Andy0"));
// table.put(put);
// table.close();
// }

3、先判断表是否存在，再来删除HBase表（生产开发首推）

package zhouls.bigdata.HbaseProject.Pool;

import java.io.IOException;

import zhouls.bigdata.HbaseProject.Pool.TableConnection;

import javax.xml.transform.Result;

public class HBaseTest {

// Delete delete = new Delete(Bytes.toBytes("row_04"));
//// delete.deleteColumn(Bytes.toBytes("f"), Bytes.toBytes("name"));//deleteColumn是删除某一个列簇里的最新时间戳版本。
// delete.deleteColumns(Bytes.toBytes("f"), Bytes.toBytes("name"));//delete.deleteColumns是删除某个列簇里的所有时间戳版本。
// table.delete(delete);
// table.close();

// Scan scan = new Scan();
// scan.setStartRow(Bytes.toBytes("row_01"));//包含开始行键
// scan.setStopRow(Bytes.toBytes("row_03"));//不包含结束行键
// scan.addColumn(Bytes.toBytes("f"), Bytes.toBytes("name"));
// ResultScanner rst = table.getScanner(scan);//整个循环
// System.out.println(rst.toString());
// for (org.apache.hadoop.hbase.client.Result next = rst.next();next !=null;next = rst.next() )
// {
// for(Cell cell:next.rawCells()){//某个row key下的循坏
// System.out.println(next.toString());
// System.out.println("family:" + Bytes.toString(CellUtil.cloneFamily(cell)));
// System.out.println("col:" + Bytes.toString(CellUtil.cloneQualifier(cell)));
// System.out.println("value" + Bytes.toString(CellUtil.cloneValue(cell)));
// }
// }
// table.close();

HBaseTest hbasetest =new HBaseTest();
// hbasetest.insertValue();
// hbasetest.getValue();
// hbasetest.delete();
// hbasetest.scanValue();
// hbasetest.createTable("test_table4", "f");
hbasetest.deleteTable("test_table4");//先判断表是否存在，再来删除HBase表（生产开发首推）

}

//生产开发中，建议这样用线程池做
// public void insertValue() throws Exception{
// HTableInterface table = TableConnection.getConnection().getTable(TableName.valueOf("test_table"));
// Put put = new Put(Bytes.toBytes("row_01"));//行键是row_01
// put.add(Bytes.toBytes("f"),Bytes.toBytes("name"),Bytes.toBytes("Andy0"));
// table.put(put);
// table.close();
// }

//生产开发中，建议这样用线程池做
// public void createTable(String tableName,String family) throws MasterNotRunningException, ZooKeeperConnectionException, IOException{
// Configuration conf = HBaseConfiguration.create(getConfig());
// HBaseAdmin admin = new HBaseAdmin(conf);
// HTableDescriptor tableDesc = new HTableDescriptor(TableName.valueOf(tableName));
// HColumnDescriptor hcd = new HColumnDescriptor(family);
// hcd.setMaxVersions(3);
//// hcd.set//很多的带创建操作，我这里只抛砖引玉的作用
// tableDesc.addFamily(hcd);
// admin.createTable(tableDesc);
// admin.close();
// }

public void deleteTable(String tableName)throws MasterNotRunningException, ZooKeeperConnectionException, IOException{
Configuration conf = HBaseConfiguration.create(getConfig());
HBaseAdmin admin = new HBaseAdmin(conf);
if (admin.tableExists(tableName)){
admin.disableTable(tableName);
admin.deleteTable(tableName);
}else{
System.out.println(tableName + "not exist");
}
admin.close();
}

public static Configuration getConfig(){
Configuration configuration = new Configuration();
// conf.set("hbase.rootdir","hdfs：HadoopMaster:9000/hbase");
configuration.set("hbase.zookeeper.quorum", "HadoopMaster:2181,HadoopSlave1:2181,HadoopSlave2:2181");
return configuration;
}
}
