Question

我有简单的HBase客户端程序在Windows 7 - 32位运行。客户端代码在这里给出：

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


public class HConnect 
{
    public static void main(String[] args) 
    {
        try
        {
            Configuration   aConfig = HBaseConfiguration.create();
            aConfig.set("hbase.zookeeper.quorum", "actual url"); 
            aConfig.set("hbase.zookeeper.property.clientPort","actual port number");



        HTable          aTable  = new HTable(aConfig, "TestTable");

        byte[]          aRowKey = Bytes.toBytes("RowKey1Mod");
        Put             aPut    = new Put(aRowKey);

        byte[]          aColFamily  = Bytes.toBytes("ColumnFamily1");
        byte[]          aColumn     = Bytes.toBytes("Column1");
        byte[]          aColumnVal  = Bytes.toBytes("ColumnValue1");

        aPut.add(aColFamily, aColumn, aColumnVal);

        aTable.put(aPut);
        aTable.close();
    }
    catch(IOException aException_in)
    {
        System.out.println("");
    }
}

}

HTable构造函数挂起，显示以下消息：

请帮忙。这花了我很多时间。
