我刚刚开始使用 hbase。我试图执行以下java程序。此代码创建一个表并向表添加一些值，但我收到以下提到的错误。
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.util.Bytes;
import java.io.IOException;
public class PutExample {
public static void main(String[] args) throws IOException {
Configuration conf = HBaseConfiguration.create();
HTable table = new HTable(conf, "testtable");
Put put = new Put(Bytes.toBytes("row1"));
put.add(Bytes.toBytes("colfam1"), Bytes.toBytes("qual1"),
Bytes.toBytes("val1"));
put.add(Bytes.toBytes("colfam1"), Bytes.toBytes("qual2"),
Bytes.toBytes("val2"));
table.put(put);
}
}
错误：
