JAVA操作HBase出錯記錄

簡介環境：

Eclipse Java EE IDE for Web Developers.（Version: Kepler Service Release 1）（Build id: 20130919-0819）

HBase （hbase-0.98.3-hadoop2-bin.tar.gz）（在虛擬機CentOS6.5中）

......可能還在運行

JAVA代碼如下：（我把Hbase中hbase-0.98.3-hadoop2\lib下的jar包都加到工程中了）

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.HBaseAdmin;

public class HBaseTest {

    public static void main(String[] agrs) throws Exception {
        String strTBName = "tb_test"; // 表
        String strColFamily = "cf"; // 列族

        // 配置
        Configuration conf = HBaseConfiguration.create();
        conf.set("hbase.zookeeper.quorum", "【這里是Master的IP值】");

        // 管理員
        HBaseAdmin hbaseAdmin = new HBaseAdmin(conf);

        // 表名稱
        TableName tableName = TableName.valueOf(strTBName);

        // 表描述器
        HTableDescriptor tableDesc = new HTableDescriptor(tableName);

        tableDesc.addFamily(new HColumnDescriptor(strColFamily));// 添加列族

        // 創建一個表，同步操作
        hbaseAdmin.createTable(tableDesc);

        System.out.println("創建表" + strTBName + "成功");
    }
}

首先我是看了這篇文章：http://javacrazyer.iteye.com/blog/1186881

其中評論11樓：（我的是按自己的配置來的）

11 樓 sujianhu 2014-04-23  
我也碰到
13/07/05 19:50:05 INFO zookeeper.ClientCnxn: Opening socket connection to server 192.168.56.101/192.168.56.101:2181. Will not attempt to authenticate using SASL (無法定位登錄配置)  
13/07/05 19:50:05 INFO zookeeper.ClientCnxn: Socket connection established to 192.168.56.101/192.168.56.101:2181, initiating session

13/07/05 19:50:06 INFO client.HConnectionManager$HConnectionImplementation: getMaster attempt 0 of 10 failed; retrying after sleep of 1008 最終找到原因是節點在zookeeper注冊的是主機名
所以在eclipse 遠程調試的時候要把windows的host文件加上節點信息例如 192.168.159.2 master master
192.168.159.3 save1 save1
192.168.159.4 save2 save2
192.168.159.5 save3 save3
這種錯誤基本都是host錯誤，查找了不少zookeeper的資料都說對ip支持很弱，所以要配置主機名與ip的映射。不然很容易錯。

改完后，再運行就可以了！

 

下面這個錯誤是因為HBase還在啟動...稍等之后再試。

hbase(main):002:0> list

Here is some help for this command:
List all tables in hbase. Optional regular expression parameter could
be used to filter the output. Examples:

  hbase> list
  hbase> list 'abc.*'
  hbase> list 'ns:abc.*'
  hbase> list 'ns:.*'
