我是hbase和hadoop的新手。
我正在ubuntu中以伪模式安装hadoop(1.2.1)和hbase(0.94.27)。
我还使用habse shell成功地创建或向hbase表插入数据。
但当我试图在eclipse中使用javaapi编写一个简单的程序来向表中插入数据时
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();
}
}
}
,出现以下错误:

我试图寻找类似的错误,但至今还没有找到解决办法。
有人遇到过这个问题吗?请帮帮我。
另外,我的hbase-site.xml
> <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>
我的/etc/主持人喜欢这样
> 127.0.0.1 localhost
> 127.0.0.1 testuser-VirtualBox
