hbase开发环境搭建及运行hbase小实例（HBase 0.98.3新api）

问题导读：
1.如何搭建hbase开发环境？
2.HTableDescriptor初始化产生了那些变化？
3.eclipse如何连接hbase集群？




hbase开发环境搭建与hadoop开发环境搭建差不多的。这里是以win7为例。
首先我们看一下hadoop的开发环境搭建，参考hadoop开发方式总结及操作指导，这里讲了两个方式，一种是用插件，另外一种是不是用插件。
那么对于hbase的开发环境是什么样子的，该如何搭建？
我们采用的是添加包的方式。
首先需要下载安装包：

1.安装包下载


可以通过官网下载：
http://mirror.bit.edu.cn/apache/hbase/hbase-0.98.3/




百度网盘下载：
hbase-0.98.3-hadoop2-bin.tar.gz
链接：http://pan.baidu.com/s/1mguTsRu 密码：xlhc


2.添加包

（1）我们解压包
解压之后，得到如下包



（2）添加包
添加包的操作



如上图5个步骤：
单击hbase-》属性弹出（2所示）Properties for hbase属性对话框.

然后我们通过下标5，单击Add External JARs。
找到hbase_home/lib，我这里是D:\hadoop2\hbase-0.98.3-hadoop2\lib




添加完毕，这样开发环境就搭建完毕。





搭建完毕，我们先做个简单的例子吧
就创建一个blog表。
1.首先通过list命令查看表





2.我们运行下面程序：

运行通过下面操作方式：

package www.aboutyun.com.hbase;

import java.io.IOException;

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.HBaseAdmin;
import org.apache.hadoop.hbase.TableName;
import org.apache.hadoop.hbase.util.Bytes;

public class OperateTable {
         public static void main(String[] args) throws IOException {
         
         Configuration conf = HBaseConfiguration.create();
         conf.set("hbase.zookeeper.quorum", "master");//使用eclipse时必须添加这个，否则无法定位
         conf.set("hbase.zookeeper.property.clientPort", "2181");
         HBaseAdmin admin = new HBaseAdmin(conf);// 新建一个数据库管理员//新api
         HTableDescriptor desc=new HTableDescriptor(TableName.valueOf("blog"));
         //HTableDescriptor desc = new HTableDescriptor("blog");
         desc.addFamily(new HColumnDescriptor("article"));
         desc.addFamily(new HColumnDescriptor("author"));
         admin.createTable(desc );
         admin.close();
         //admin.disableTable("blog");
         //admin.deleteTable("blog");
         //assertThat(admin.tableExists("blog"),is(false));
   }
}

注释：
   conf.set("hbase.zookeeper.quorum", "master");//使用eclipse时必须添加这个，否则无法定位
这里因为使用的是win7，所以master需要配置hosts。如下图所示




hosts的路径为C:\Windows\System32\drivers\etc







得到结果：我们看到blog就创建成功了。



这里说一下：
HTableDescriptor的初始化发生变化：


新API
  HTableDescriptor desc=new HTableDescriptor(TableName.valueOf("blog"));
旧API
  HTableDescriptor desc = new HTableDescriptor("blog");

hbase中每个存储单元cell为何允许存储数据的多个版本啊？求解

ascentzhen 发表于 2014-8-5 18:34
hbase中每个存储单元cell为何允许存储数据的多个版本啊？求解

这是大数据的特点，保留多个副本，作用有很多，比如防止数据丢失

哦，好的，多谢

非常感谢，楼主能指点一下，hbase如何进行模糊查询吗？

牛叉，赞一个，动手搭建一下，感谢楼主的分享。

配置失败了，win下面的host文件内容：
192.168.0.101                  hadoop1
192.168.0.102                  hadoop2
192.168.0.103                  hadoop3
192.168.0.104                  hadoop4
192.168.0.105                  hadoop5

                Configuration conf = HBaseConfiguration.create();

                conf.set("hbase.master", "hadoop1");

                conf.set("hbase.zookeeper.property.clientPort", "2181");
                // 实例化一个客户端
                HTable table = new HTable(conf,"testtable");
               
                // 指定一个行来创建一个Put
                Put put = new Put(Bytes.toBytes("row1"));

                // 向put中添加两个列
                put.add(Bytes.toBytes("cf"), Bytes.toBytes("col1"), Bytes.toBytes("val1"));
                put.add(Bytes.toBytes("cf"), Bytes.toBytes("col2"), Bytes.toBytes("val2"));
               
                table.put(put);
               
        }

}

好郁闷啊，更楼主一样的配置，不知道为什就不行。迫切希望能得到您的指点
