HBase编程 API入门系列之delete（管理端而言）（9）

2017-11-12 617

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>

HBase编程 API入门系列之modify（管理端而言）（10）

　这里，我带领大家，学习更高级的，因为，在开发中，尽量不能去服务器上修改表。所以，在管理端来修改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(){ } priv...

　这是从程度开发层面来说，为了方便和提高开发人员。这个工具Bytes类，有很多很多方法，帮助我们HBase编程开发人员，提高开发。这里，我只赘述，很常用的！ 1 package zhouls.bigdata.HbaseProject.Tool; 2 3 import org.apache.hadoop.hbase.util.Bytes; 4 5 public class BytesTest { 6 public static void main(String[] args) { 7 byte b[] = Bytes.toBytes("maizi"); 8 byte a[] = Bytes.toBytes("hello"); 9 10 // 多个字节，拼装成一个row key 11 byte c[] =Bytes.add(a,b); 12 System.out.println(Bytes.toString(c)); 13 } 14 } hellomaizi 1 package zhouls.bigdata.HbaseProject.Tool; 2 3...
