40 ......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");
    }
}

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！

新浪微博数据解析与java操作Hbase实例

之前发过一篇开发新浪微博的文章,对于大家比较感兴趣的内容之一便是如何解析新浪微博的JSON. 其实一开始的时候,也遇过一些挫折,比如直接用JsonArray和JsonObject去解析JSON内容的话,是解析不了的. 因为JSON的格式比较固定,像新浪微博返回的JSON内容则是多了一个中括号及statues标签,如下: { "statuses": [ { "created_at": "Tue May 31 17:46:55 +0800 2011"

Java操作hbase总结

用过以后,总得写个总结,不然,就忘喽. 一.寻找操作的jar包. java操作hbase,首先要考虑到使用hbase的jar包. 因为咱装的是CDH5,比较方便,使用SecureCRT工具,远程连接到你安装的那台服务器上. jar包的存放位置在/opt/cloudera/parcels/CDH/lib/hbase,找到,下载下来. 在当前路径下,有一个lib包,里面是支持hbase的hadoop的jar包,根据需求,可以下载下来. 二.找一个API文档当成手册,哪里不会查哪里 百度分享,http
