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)
Caused by: java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory

最佳答案
您需要commons-logging项目类路径中的库。
