......可能还在运行

JAVA代码如下：（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", "【这里是Master的IP值】");

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

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

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

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

// 创建一个表，同步操作
hbaseAdmin.createTable(tableDesc);

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

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

其中评论11楼：（我的是按自己的配置来的）

11 楼 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 (无法定位登录配置)
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
最终找到原因是节点在zookeeper注册的是主机名
所以在eclipse 远程调试的时候要把windows的host文件加上节点信息例如
192.168.159.2 master master
192.168.159.3 save1 save1
192.168.159.4 save2 save2
192.168.159.5 save3 save3
这种错误基本都是host错误，查找了不少zookeeper的资料都说对ip支持很弱，所以要配置主机名与ip的映射。不然很容易错。

改完后，再运行就可以了！

下面这个错误是因为HBase还在启动...稍等之后再试。

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:.*'

解决是修改hosts文件（系统盘:\Windows\System32\drivers\etc）：

*.*.*.* s1 s1
*.*.*.* s2 s2
