一、应用线程导入

    1、创建put方法

public class mmm{	public static Configuration config=new Configuration();;	static{		config.set("hbase.zookeeper.property.clientPoint","2181");		config.set("hbase.zookeeper.quorum","hbase");		config.set("dfs.socket.timeout", "180000");	}    public static void put(String tablename,String RowKey,String Family,String Qualifier,String Value){    HTable h=null;    try{        h=new HTable(config,tablename);        Put put=new Put(Bytes.toBytes(RowKey));        put.add(Bytes.toBytes(Family), Bytes.toBytes(Qualifier), Bytes.toBytes(Value));        h.put(put);    }catch(Exception e){e.printStackTrace();}finally{        try {        h.close();        } catch (IOException e) {            e.printStackTrace();            }        }    }}

    2、创建线程

    public class PutXX {    public static void main(String[] args) {        run1 r1=new run1();        Thread rr1=new Thread(r1);        rr1.start();        run2 r2=new run2();        Thread rr2=new Thread(r2);        rr2.start();        //这里创建两个线程，需要可以继续创建~}}class run1 implements Runnable{public void run() {for(int i=0;i<=10000000;i++){    mmm.put("yuan", ""+i+"", "property", "yuan_name", "xx"+i);    System.out.println(i);    }}}class run2 implements Runnable{public void run() {for(int i=10000001;i<=20000000;i++){    mmm.put("yuan", ""+i+"", "property", "yuan_name", "xx"+i);    System.out.println(i);    }}}

    <2015.2.2>

    数据导入速度慢。之前put方法每执行一次就要new一个新HTable然后释放资源。。太墨迹了

    新put

public static void NBput(String tablename,int RowKey,String Family,String Qualifier,String Value){        HTable h=null;        try {            h=new HTable(config,tablename);            for(int i=RowKey;i<=(RowKey+10000000);i++){            String row=""+i+"";            Put put=new Put(Bytes.toBytes(row));            put.add(Bytes.toBytes(Family), Bytes.toBytes(Qualifier), Bytes.toBytes(Value));            h.put(put);            System.out.println(i);        }            } catch (IOException e) {                e.printStackTrace();            }finally{            try {                h.close();            } catch (IOException e) {                e.printStackTrace();            }        }    }

        修改以后速度明显提升啊我去！之前那方法太傻缺了。。。。

二、使用List进行put

    public class mmm{    public static Configuration config=new Configuration();;	static{		config.set("hbase.zookeeper.property.clientPoint","2181");		config.set("hbase.zookeeper.quorum","hbase");		config.set("dfs.socket.timeout", "180000");	}	/*	 * 批量put	 * 	 */	public static void moreput(String tablename, List
     
       puts){		HTable h=null;		try{			h=new HTable(config,tablename);			Put put=new Put(Bytes.toBytes(""));			puts.add(put);			h.put(puts);		}catch(Exception e){			e.printStackTrace();		}finally{			try {				puts.clear();				h.close();			} catch (IOException e) {				e.printStackTrace();			}		}	}}
     

    然后在主函数中：

             List
     
       puts=new ArrayList
      
       ();    for(int i=100000;i<=5000000;i++){        System.out.println(i);        Put put=new Put(Bytes.toBytes(""+i+""));        put.add(Bytes.toBytes("property"), Bytes.toBytes("yuan_name"), Bytes.toBytes("源网"+i));        puts.add(put);}    System.out.println("写入List完成");    mmm.moreput("yuan", puts);
