我尝试从 java 以本地模式连接 HBase 但在调试时报告错误。我的代码：

import java.io.IOException;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.client.Get;
import org.apache.hadoop.hbase.client.HTable;
import org.apache.hadoop.hbase.client.Put;
import org.apache.hadoop.hbase.client.Result;
import org.apache.hadoop.hbase.client.ResultScanner;
import org.apache.hadoop.hbase.client.Scan;
import org.apache.hadoop.hbase.util.Bytes;
import org.apache.hadoop.conf.Configuration;


public class MyLittleHBaseClient {
  public static void main(String[] args) throws IOException {

    Configuration config = HBaseConfiguration.create();
    HTable table = new HTable(config, "test");
    ....

和错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
at org.apache.hadoop.conf.Configuration.<clinit>(Configuration.java:129)
at mylittlehbaseclient.MyLittleHBaseClient.main(MyLittleHBaseClient.java:32)

您需要项目的类路径中的commons-logging库。
