無法從java連接到hbase

Question

我已經設置了一切，就像hbase文檔所述。這裏是我的HBase-site.xml中

<configuration> 
    <property> 
     <name>hbase.rootdir</name> 
     <value>file:///users/urijvoskresenskij/hbase-0.94.3/hbase</value> 
    </property> 
    <property> 
     <name>hbase.zookeeper.property.dataDir</name> 
     <value>/users/urijvoskresenskij/hbase-0.94.3/zookeeper</value> 
    </property> 
</configuration> 

Java代碼：

import java.io.IOException; 

import org.apache.hadoop.conf.Configuration; 
import org.apache.hadoop.hbase.HBaseConfiguration; 
import org.apache.hadoop.hbase.client.HBaseAdmin; 
import org.apache.hadoop.hbase.client.HTable; 
import org.apache.hadoop.hbase.client.Put; 
import org.apache.hadoop.hbase.util.Bytes; 

public class MainHBase { 

    /** 
    * @param args 
    */ 
    public static void main(String[] args) throws Exception { 
     Configuration config = HBaseConfiguration.create(); 
     config.set("hbase.zookeeper.quorum", "localhost"); 
     HBaseAdmin admin = new HBaseAdmin(config); 
     try { 
      HTable table = new HTable(config, "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(); 
     } 
} 

這裏是例外：

試過已谷歌，但沒能找到解決方案。我的操作系統是OS X.我嘗試創建的表格無法從hbase shell掃描。請幫忙:)

Answer 1

你有沒有創建「測試表」？表格必須在將數據放入之前存在。

Configuration conf = HBaseConfiguration.create(); 
HBaseAdmin hbase = new HBaseAdmin(conf); 
HTableDescriptor desc = new HTableDescriptor("test_table"); 
HColumnDescriptor cf = new HColumnDescriptor("cf".getBytes()); 
desc.addFamily(cf); 
hbase.createTable(desc);
