在ubuntu上運行eclipse中的Hbase示例

Question

我是Hbase和Hadoop中的新手。

我在Ubuntu中以僞模式設置Hadoop（1.2.1）和hbase（0.94.27）。

我也使用habse shell成功創建或插入數據到hbase表。

15/05/30 01:24:20 INFO zookeeper.ZooKeeper: Initiating client connection, connectString=localhost:2181 sessionTimeout=180000 watcher=hconnection0x0

我試圖尋找類似：

但是，當我嘗試寫一個簡單的程序在Eclipse中

public class HbaseTest { 
    public static void main(String[] args) throws Exception { 
     Configuration conf = HBaseConfiguration.create(); 
     HBaseAdmin admin = new HBaseAdmin(conf); 
     try { 
      HTable table = new HTable(conf, "test-table"); 
      Put put = new Put(Bytes.toBytes("test-key")); 
      put.add(Bytes.toBytes("cf"), Bytes.toBytes("q"), Bytes.toBytes("value")); 
      table.put(put); 
     } finally { 
      admin.close(); 
     } 
    } 
} 

使用Java API將數據插入到表，我下面得到這個錯誤錯誤，但目前尚未找到解決方案。

有沒有人有這個問題的經驗？請幫幫我。

另外，我的HBase-site.xml中這樣

> <configuration> <property> 
>   <name>hbase.rootdir</name> 
>    <value>hdfs://localhost:54310/hbase</value> 
>  </property> 
>  <property> 
>  <name>hbase.zookeeper.property.dataDir</name> 
>  <value>/home/hduser/zookeeper</value> 
>  <description>Property from ZooKeeper's config zoo.cfg. 
>  The directory where the snapshot is stored. 
>  </description> 
>  </property> </configuration> 

這樣

> 127.0.0.1 localhost 
> 127.0.0.1 testuser-VirtualBox
